When a series of Jimi Hendrix albums were re-released earlier this year, they each included an insert detailing other reissues in the series, and some existing Hendrix LP’s ‘the listener might enjoy’. The insert listed about five or six records. But go onto Wikipedia, and look at the “Posthumous Discography” and you will see somewhere in the region of not six albums, but about SIXTY. So why is this? Why has the greatest guitarist of all time got a confusing list of releases hidden away? Well, to mark his death which occured 40 years ago this month, in this article, I shall attempt to explain how the Hendrix back catalogue falls into “authorised” and “semi-official” releases, and to try to clarify what the Hendrix discography more or less looks like, once you understand what was released, when, and by whom.
Hendrix In His LifetimeWhat is often overlooked is that not one of the studio albums Hendrix released before his death were billed as solo records at all, but were all credited to “The Jimi Hendrix Experience”, a trio which also featured Mitch Mitchell on Drums, and Noel Redding on Bass. All were British, except Hendrix, and they had ex-Animals musician Chas Chandler as their manager. They released three albums in the space of two years - 1967’s “Are You Experienced”, “Axis Bold As Love” (issued in 67 in the UK, 68 in the US), and 1968’s “Electric Ladyland”. Soon after, internal rows split the band, and the Experience ceased to exist in 1969. Jimi went on to form several subsequent bands, the second of which, The Band Of Gypsys, featured Hendrix alongside Billy Cox and Buddy Miles. An earlier contract signed by Jimi meant he was required to record an LP for Capitol Records in the US, and the decision was taken to tape all four of the shows the band played during New Years Eve 1969 and New Years Day 1970. In order to avoid including previously recorded Experience material on the subsequent LP, several new numbers had been written and were performed during the gigs, enough to fill up a single album (the band did still perform a sizeable number of Experience songs as well, to avoid upsetting their audiences). The resultant album was called “Band Of Gypsys”, but was credited as a Hendrix solo album - with a picture of Jimi on the cover, and nothing other than the name “Hendrix” on the front of the sleeve.
The group lasted barely six weeks - by the summer of 1970, a new line up of the Experience were touring, with Hendrix, Cox and Mitchell, but Hendrix passed away on September 18th 1970 and left behind what was, at the time, a fairly slim back catalogue. In addition to the four albums and a select number of singles, the only other album released during Jimi’s lifetime was the Greatest Hits set, “Smash Hits”, cobbling together non-album A sides and B sides along with selected album tracks to pad it out to the length of a vinyl LP.
The three “Experience” albums have all been reissued numerous times over the years - the band’s early 45’s consisted of material not available on album, but the debut LP has had it’s tracklisting altered by different labels in different countries over the years, so the likes of “Hey Joe” will often appear - either as a bonus track, or as part of the “normal” album. “Electric Ladyland” was originally issued in the famous “nudes” sleeve, but as time has passed, it seems the record labels have gotten more ‘Mary Whitehouse’ and the 2010 reissue is one of several recent pressings of this record to use a close-up picture of Jimi onstage instead. By this time in the band’s career, they had stopped doing B-sides, which is just as well - being a double album, there would be no space on a CD of “Ladyland” to include any extra material. Despite several best of’s being released over the years, “Smash Hits” is still considered to be a good overview of the band on 45, and has also benefited from a 2010 reissue, as has “Band Of Gypsys”.
The Posthumous Studio RecordsIn addition to the live album, Band Of Gypsys did go into the recording studio with a view to releasing what would have been the fifth Hendrix album (or, if you prefer, the fourth studio album). In the States, Reprise issued a single consisting of two recordings from the sessions, “Stepping Stone” and “Izabella”. However, soon after, the single was withdrawn, apparently to avoid damaging sales of the “Band Of Gypsys” LP. Jimi himself felt that both songs lacked something special, and the reformed Experience later went into the studio to re-work the tracks, but the new versions remained unissued at the time of Hendrix’s death.
At the time of Hendrix’s passing, he had amassed enough material to fill up another double album, and was only a matter of weeks away from offering up material for his label to release as his next studio LP. Various sources claim it was to either be called “Strate Ahead” or “First Rays Of The New Rising Sun”, and given that there was a myriad of different musicians involved, looked likely to be issued as a “Jimi Hendrix“ solo album. It was no surprise then, that in 1971, a (single) album’s worth of material was released in both the UK and US called “The Cry Of Love”. It was the first of three albums of unreleased studio recordings that would appear in the next couple of years. The follow up, “Rainbow Bridge”, was issued later the same year, and consisted of more material from the never-released fourth studio album. However, several tracks from other sources were used to pad out the album - there was even a live recording of “Hear My Train A Comin’” (not too much of a shock, given that “Rainbow Bridge” was the name of a set of concerts Hendrix performed in Hawaii in 1970). The remainder of the “First Rays” material appeared in 1972 on “War Heroes” - there were only three songs from those sessions on the album (including the re-recorded “Izabella” and “Stepping Stone”), and that should really have been the end of the matter.
Another album of outtakes, “Loose Ends”, was issued by Polydor in 1974. Many fans believed that there was a great deal of barrel scraping going on - aside from a B-side, “The Stars That Play With Laughing Sam’s Dice”, and a finished but not issued Bob Dylan cover, the rest was deemed to be sub-standard material that, had Jimi not died, would either have been re-recorded, or would not have been authorised for release at all. In the US, Jimi’s then label Warner Brothers, actually refused to release the album.
A change of management by 1975 saw the situation worsen - more unissued material was released, but this time, session musicians were drafted in to help “complete” unfinished demos, and the next release “Crash Landing” was condemned by Hendrix watchers. Another album along the same lines, “Midnight Lightning”, was released later the same year. The follow-up, “Nine To The Universe”, surfaced in 1980 - it did not suffer from having extra musicians on it to help fatten out the sound, and was the last posthumous studio album to appear in the 20th Century.
In the mid 1990s, relatives of Hendrix were rather concerned at the haphazard nature of the material released since Jimi’s death. In a concerted effort to try and control what was being released (both in terms of studio and live material), Experience Hendrix was formed. A deal was struck with MCA, with the family estate having the final say on what material could or could not be released. The deal covered reissues of existing albums, new compilation albums, and live albums - most of the live releases would actually be issued through a specialist label, Dagger Records (which took it’s name from the “First Rays” outtake, “Dolly Dagger”). Any release that was felt to be of interest to the collector, rather than the casual fan, would be issued through this label - and as such, some studio material was released on Dagger rather than MCA.
One of the first projects of the estate was to try and put all of the “First Rays” material together on a single CD - an earlier release had been put out by MCA called “Voodoo Soup”, but included items from other sessions so was not a true attempt at issuing what the fourth Hendrix studio LP would have sounded like had Jimi not died. In 1997, “First Rays Of The New Rising Sun” was issued by MCA and Experience Hendrix, a 70-minute long release which aimed to include, in the order he had reportedly intended, all of the material Jimi was proposing to put on that fourth album back in 1970. There was some controversy over the inclusion of “My Friend”, given that it had been recorded several years earlier, and some claimed it had remained unissued for a reason, and that it was not likely to have been included on Jimi’s planned version of “First Rays” - at least not in it’s original form. Nevertheless, the 1997 album did a good job of collating this material, and is now seen in the Experience Hendrix camp as being the official follow-up to “Band Of Gypsys”. A second release that year, “South Saturn Delta”, tended to veer towards the odds and sods, rather than material that was being planned for a specific LP, and is now thought of as the only “official” rarities set still on catalogue.
2010’s “Valleys Of Neptune” is a strange one - it’s being touted as “a new Hendrix” album, the follow-up to “First Rays”, but is actually closer in feel to “South Saturn Delta” - especially as it consists of re-recordings of already available tracks such as “Fire” and “Stone Free”.
Despite the formation of the estate, a series of albums (both live and studio) have surfaced at an alarming rate on a variety of other labels, including the dubiously named Purple Haze Records. This has come about as people who worked with Hendrix when he was alive claim to own the rights to release selected material - something which Experience Hendrix have disputed. These releases have appeared officially on Amazon, or in HMV, but there have been several “cease and desist” cases from the estate towards the labels responsible for these releases. Whilst many titles have thus been deleted, the material issued has usually then re-surfaced on a different title, and sometimes on a different label. Experience Hendrix have authorised the release of a handful of live tracks from gigs such as the ‘Rainbow Bridge’ concerts and the Royal Albert Hall 1969 show, but not the entire performances - it has been up to these “unofficial” albums to plug the gap. More details about Hendrix’s live outings are listed later in this blog.
SinglesEven the passing observer will know a few Hendrix tunes, helped along by the fact that Jimi released several singles in the 60’s that contained his most iconic material. The first three 45’s issued in the UK consisted of material not included (originally) on the debut Experience LP - “Hey Joe”/”Stone Free”, “Purple Haze”/”51st Anniversary” and “The Wind Cries Mary”/”Highway Chile”. The US did things differently, and issued the lead track of “Are You Experienced”, “Foxy Lady”, as an A-side, but the UK issued no “Experienced” tracks as singles, as the fourth JHE 45 was a new recording, “Burning Of The Midnight Lamp” (backed with the aforementioned “The Stars That Play…”). “Midnight Lamp” would eventually appear on the “Electric Ladyland” LP - a strange move, given that the single was actually issued before the SECOND LP, “Axis Bold As Love”.
In the US, several songs from “Axis” were issued as singles, but with the release of the “Electric Ladyland” track, “All Along The Watchtower”, the choice of A-sides in the US matched the choices in the UK - although the B-sides still tended to differ. Both countries issued another “Ladyland” track, “Crosstown Traffic”, as a follow-up, and although nobody knew it at the time, this would turn out to be the last "proper" UK single to be issued whilst Hendrix was alive.
There were some rather strange singles released thereafter - tracks from the “Experienced” period were issued during 1969, before the US only Reprise release of the aforementioned “Stepping Stone” 7” - the last American single issued before Jimi’s death. Track Records in the UK decided to commemorate Jimi’s life with the release late in 1970 of “Voodoo Chile” - the single was released as a 3-track Maxi Single, issued at a low price in a picture sleeve, a rarity at the time in the UK. Despite including no new material, the single proved incredibly popular, and went to number 1. Despite selling in huge numbers, the fact that Track had issued it in a picture sleeve at reduced cost meant the single possibly lost the label money rather than making them any!
There have been more 45’s issued after Jimi’s death than before it, although most of them were released in connection with whatever cash-in compilation was in the shops at the time, so most contain material lifted from the relevant album. As I don’t own too many of these releases, I can’t comment on them in too much detail, so I won’t go into everything that was released in this blog. The two most notable releases are 1971’s “No Such Animal”, which doesn’t seem to have been compiled on an album at the time (despite what Wikipedia says, it was released in both the UK and the US, appearing on RCA in the UK) and 2010’s “Bleeding Heart”, which included an unreleased take of “Peace In Mississippi” on the flip.
At least two singles box sets have been issued via Experience Hendrix in the UK. The first of these, “Classic Singles Collection”, was issued towards the end of the 90’s. It consisted of 10 7” singles, each housed in an exotic foreign picture sleeve - although unlike the singles box sets you get nowadays, no attempt was made to re-create either the original labels or the rear of the picture sleeves, with a custom label and custom rear sleeve used on each single, each utilising the same type-face. This most likely was because even though many countries issued 45’s in picture sleeves in the 60’s and 70’s, the rear cover was often the same as the front. The set also included one posthumous single, “Freedom”. The booklet was rather confusing - it claimed everything on the box was from either “Experienced”, “Axis”, “Ladyland” or “First Rays”, but as mentioned earlier, the likes of “Hey Joe” were only ever available on LP in selected territories or as bonus tracks only. As a UK Hendrix fan, I don’t view “Hey Joe” as being from “Are You Experienced” - I have a 1970’s mono reissue of that LP on vinyl, and it is (correctly) not on there! Similarly, the tracks from “First Rays” (both sides of the “Freedom” 7”) added to the confusion - according to Wikipedia (again), the material on the 1997 edition of “First Rays” had been slightly tweaked since the tracks had originally been released on the likes of “Cry Of Love”, “Rainbow Bridge” and “War Heroes”, meaning that either:
1) this edition of the single used the original mixes, but overlooked this
2) this edition of the single, controversially, used the new mixes
3) Wikipedia is wrong, and it’s the same mixes on both “First Rays” and “Cry Of Love”
Can anybody enlighten me? I believe the confusion is primarily that the 1997 edition is a “remaster”, which adds some clarity to the sound, but nothing else.
A second box set, this time on CD, called “The Singles Collection”, surfaced in 2003. This included reissues (with back covers intact) of the first four 45’s issued in the UK (but in foreign sleeves once more). Also included were the US only singles “Foxy Lady” and “Stepping Stone”, along with two other singles released in the UK towards the end of the 60s/start of the 70s - “Crosstown Traffic” and the aforementioned “Voodoo Chile” maxi-single. Also included was the previously promo-only “Dolly Dagger” and the slightly bonkers “Little Drummer Boy” EP, complete with Jimi in Santa Claus outfit on the front!
Aside from the mountain of “official” releases shown on Wikipedia, there are an equally huge amount of unauthorised (but not bootleg) releases covering outtakes and live gigs on the market. There are links below to one fansite which goes into these releases in greater detail.
Just as a taster as to what exists; there are some intriguing re-releases of all three original studio albums with new covers, alternate titles, and bonus tracks on a second CD (such as “Are You Experienced And More”). Plenty of studio outtakes exist, often issued in a myriad of formats to grab the collector - a huge wad of unissued material from the sessions of “Axis Bold As Love” formed the basis of “Axis Outtakes” in 2003 - this release appeared as a double CD, and each disc was also individually released on vinyl as “Axis Outtakes 1” and “Axis Outtakes 2”. Both these releases were also issued as Picture Discs in clear see through sleeves as well - and this is only the tip of the iceberg!
After Hendrix’s death, some live albums appeared on Polydor such as “Isle Of Wight” in the early 70s, whilst other releases first appeared in the CD era on the same label, such as “Jimi Plays Monterery”. In recent years, the amount of material being released has exploded - with some gigs being released in part or in full by both Experience Hendrix AND the likes of Purple Haze Records, whilst both the IOW and Monterey gigs have been reissued again in recent years via MCA or Dagger.
Rather than just list a series of album titles that might not mean much, I have listed below what I believe is every Hendrix gig that was taped and has been released in part or in full via either Polydor, MCA, or any “unofficial” label. In some cases, the listed release may only include one song from the show (such as the best-of collection “Cornerstones“, which has a pair of live tracks at the end) - others feature the entire show. I suggest if you do think about trying to collect some (or all) of these, you do a bit of research via the links below, which give track listings for each release.
Note: just after I’d finished doing this list, I found by accident something similar elsewhere on the net, so whilst the two lists should be the same, my apologies if there are some errors! Also note that on some dates, Hendrix and his band also played a matinee show, but I have not differentiated between different sets as I am not 100% sure which shows are featured on these releases.

This really is just a taster of the world of Hendrix. It hopefully makes his confusing catalogue a bit easier to understand, although the live album situation is possibly so far out of hand, that area of his work may never be fully “tidied up”. Listed below is what, more or less, is the “officially” recognised albums and singles discography.
“EXPERIENCE HENDRIX” AUTHORISED ‘ORIGINAL ALBUMS’ LP DISCOGRAPHY

South Saturn Delta (CD, 1997, MCA MCD 11684)
Valleys Of Neptune (CD, 2010, MCA 88697 640562)
“Are You Experienced”, “Axis Bold As Love”, “Electric Ladyland” and “First Rays Of The New Rising Sun” were all reissued in 2010 with a bonus “making of the album” DVD, consisting of archive footage and interviews with band members and associates. The “Experienced” reissue includes the A and B sides of the first three UK 45’s, “Ladyland” comes in the “Jimi On Stage” sleeve. “Smash Hits” and “Band Of Gypsys” were reissued in digipack sleeves as well, but with no extras. The insert which was included in the reissues and “Valleys Of Neptune” also made reference to the “Experience Hendrix” Greatest Hits CD, and the “Live At Woodstock” DVD. “South Saturn Delta” seems to be, technically, off catalogue.
Alternate/expanded versions of many of these records have been released both in an authorised and unauthorised form over the years. Aside from the aforementioned “Are You Experienced And More”, there are also releases such as “Axis Bolder Than Love”, which included a period gig on the second CD, and “Electric Ladyland And Beyond”, which like “And More” features alternate takes on CD2.
The US version of “Smash Hits” was released in 1969, which included a different take of “Red House” - which, slightly strangely, is included instead of the original mix on the “Are You Experienced And More” release. “Band Of Gypsys” was reissued with extra tracks - and Experience era songs at that - on CD in 1991, although these recordings were also included on the posthumous live album “Band Of Gypsys 2”. An even more expanded edition exists called “Live At The Fillmore East”, although bizarrely, some of the original recordings from “Band Of Gypsys” are not on this set. The origin of the material on “First Rays”, “South Saturn Delta” and “Valleys Of Neptune” can be traced back to the previously released set of records from “The Cry Of Love” through to “Nine To The Universe”.

I have not listed any of the other multitude of Hendrix releases, although I would like in a future blog to try and concentrate on specific releases (such as the numerous “Isle Of Wight” releases). For now, the links below will go into greater deal about the Dagger Records releases, and the “unofficial” live /studio albums issued without the permission or sometimes knowledge of Experience Hendrix.
