Highlighting the effort will be its title track, which was said to be unearthed nearly 40 years after it was recorded at Hendrix’s final sessions. Covers of “Bleeding Heart” and Cream’s “Sunshine of Your Love,” plus rerecorded versions of “Fire”, “Red House” and “Stone Free” are also set to be included.

“My brother Jimi was at home in the studio. Valleys of Neptune offers deep insight into his mastery of the recording process and demonstrates the fact that he was as unparalleled a recording innovator as he was a guitarist,” explains Janie Hendrix. “His brilliance shines through on every one of these precious tracks.”

The family also intends to reissue all the Jimi Hendrix Experience’s studio albums, 1967’s Smash Hits, and the 1997 release of First Rays of the Rising Sun in the months ahead. The releases will be packaged with a documentary by Beatles Anthology director Bob Smeaton and will feature interviews with the Experience’s Mitch Mitchell, Noel Redding, and producers Chas Chandler and Eddie Kramer.

Of course, all this will follow a previously announced new Hendrix live album, tribute tour, and fictionalized film. 2010 marks the 40th anniversary of the death of the acclaimed musician.
