On March 9, Sony Legacy Recordings will release a new posthumous Jimi Hendrix album called Both Sides of the Sky. The 13-track LP consists of songs recorded between 1968 to 1970, including 10 previously unheard recordings like a 1969 cover of Joni Mitchell’s “Woodstock.” It features guest collaborations with Stephen Stills, Lonnie Youngblood, Jonny Winter, and Billy Cox and Buddy Miles from Hendrix’s Band of Gypsys lineup. Both Sides of the Sky is the final installment in a trilogy series of unissued archival Hendrix recordings—it follows People, Hell and Angels (2013) and Valleys of Neptune (2010). The record was co-produced by Hendrix’s frequent engineer Eddie Kramer, John McDermott, and his sister Janie Hendrix.
