Stephen Stills is one of the last remaining music legends from the rock era without a biography. During his six-decade career, he has played with all the greats. His career sky-rocketed when Crosby, Stills & Nash played only their second gig together at Woodstock in 1969. With the addition of Neil Young, the band would go on to play the first rock stadium tour in 1974. Stephen Stills is the only person to have been inducted twice in one night into The Rock and Roll Hall of Fame.
