"Voodoo Chile" took the funky blues of greats like Muddy Waters and John Lee Hooker into the psychedelic age, the 15-minute track putting Jimi Hendrix's guitar improvisations into a loose jam-like setting. Backing him were Jimi Hendrix Experience drummer Mitch Mitchell, Jefferson Airplane bassist Jack Casady (subbing for usual Experience bassist Noel Redding) and Traffic's Stevie Winwood on organ, with guitarist Larry Coryell declining an invitation to join them. "Jimi asked me to play," Coryell recalled, "but for the first time in my life, I said, 'No. There is nothing I can add to this.'"
