[NEW RELEASE] JIMI HENDRIX

Elvis has left the building, but Jimi is still busy in the studio. Or so it would seem from the staggering number of posthumous Hendrix albums that record labels, bootleggers and - for the past two decades - his family have been releasing since his death in 1970.

“Both Sides of the Sky’’ is billed as the last in a trilogy that gathers assorted Hendrix studio recordings, following 2010’s “Valleys of Neptune’’ and 2013’s “People, Hell and Angels.’’ Nearly the whole batch comes from sessions at New York’s Record Plant between Jan. 1968 and Feb. 1970.’

Ten of the 13 tracks are billed as previously unreleased, though several are alternate or instrumental versions of known Hendrix tracks.

A take on Joni Mitchell’s “Woodstock,’’ recorded just 42 days after the end of the festival, features Hendrix on bass, with vocals and organ by Stephen Stills. It sounds like a demo of the track released by Crosby, Stills, Nash & Young some five months later. Hendrix switches to guitar on another Stills tune, “$20 Fine,’’ which also sounds very CSN&Y. Or, rather, “CSNY&H.”
