2. Jimi Hendrix
Jimi Hendrix was in pretty rough shape when he toured Europe in the summer of 1970. Burned out from endless roadwork and heavily addicted to drugs and alcohol, Hendrix played some rather sloppy shows – once even leaving the stage after just two songs. The tour wrapped up September 6th, 1970 at the Isle of Fehmarn Festival in Germany. There's no video of the gig, but here's audio of "All Along The Watchtower" from the show.
