Arlo Guthrie
Arlo Guthrie is the son of folk legend Woody Guthrie and composer Marjorie Guthrie. Arlo's song "Alice's Restaurant Massacree" depicts anti-war propaganda, and earned him a spot among counter-culture musicians. He earned a recording deal and played small venues before his ultimate gig at Woodstock.
Sly Stone
Sly, of Sly and the Family Stone, turned folksy Woodstock into a funkadelic party. Sly was raised right in the middle of the hippie movement's base in the San Francisco bay area. He had mastered four instruments by the time he was eleven, and his band exemplified everything that hippies were fighting for.
