“We’ve been doing new tracks that are really fantastic and we’ve just been getting into them,” Jimi Hendrix told Rolling Stone in February 1968, right after he and the Experience had played San Francisco’s Fillmore West. “You have these songs in your mind. You want to hurry up and get back to the things you were doing in the studio, because that’s the way you gear your mind….We wanted to play [the Fillmore], quite naturally, but you’re thinking about all these tracks, which is completely different from what you’re doing now.”  No one knew it at the time, but the new tracks Hendrix was referring to — which he, bassist Noel Redding and drummer Mitch Mitchell had been working on intermittently since the previous summer — would form the nucleus of Electric Ladyland, the sprawling double album that would finally see the light of day October 16th, 1968.  On November 9th, Sony Legacy will offer additional insight into the multi-layered and -hued work with the release of a massive 50th-anniversary box set that includes outtakes, demos, a new 5.1 surround-sound mix by Electric Ladyland engineer Eddie Kramer and the 1987 documentary At Last … the Beginning: The Making of Electric Ladyland.
