Janis Joplin, once an outcast from Port Arthur, Texas, becomes rock's most electrifying voice. Archival footage chronicles her journey from early TV appearances with Big Brother & the Holding Company, to a mind-blowing 1967 Monterey Pop performance, an explosive 1969 Woodstock set, and a candid Dick Cavett interview revealing the warm, wounded woman behind the bluesy wail. © 1974 Universal Studios.
