There are hundreds of posthumous Jimi Hendrix releases, but the first two albums to come out after the guitar legend’s death — The Cry Of Love and Rainbow Bridge — have languished in relative obscurity for years. That’s all going to change next month when both Cry Of Love and Rainbow Bridge will be re-released and remastered on CD, LP, and digital formats.

Both albums came out shortly after Hendrix’s death in 1970; as a result, both albums are regarded with some esteem by Hendrix aficionados due to the fact that many of the songs were finished or close to finished by the time of their release. Cry Of Love, which was recorded between December 1969 and the summer of 1970, was originally intended to be part of a double album that Hendrix intended to call First Rays Of The New Rising Sun. That album was assembled by the Hendrix estate in 1997, so Cry Of Love fell out of print as a result.

Rainbow Bridge, which has never been released on CD before, is not the soundtrack to the Hendrix concert film of the same name (though its title would have you believe otherwise). The album does have the studio version of one of Hendrix’s most famous covers: “The Star-Spangled Banner.” It also features a guest appearance from The Ronettes on “Earth Blues.”

Both Cry Of Love and Rainbow Bridge will be released on September 16th.
