Janis Joplin brought her powerful, bluesy voice from Texas to San Francisco's psychedelic scene, where she went from drifter to superstar. She has been called "the greatest white urban blues and soul singer of her generation." Joplin's vocal intensity proved a perfect match for the high-energy music of Big Brother and the Holding Company, resulting in a mix of blues, folk and psychedelic rock. Joplin's tenure with Big Brother may have been brief, lasting only from 1966 to 1968, but it yielded a pair of albums that included the milestone Cheap Thrills. Moreover, her performance with Big Brother at 1967's Monterey International Pop Festival, a highlight of the film documentary Monterey Pop, is among the great performances in rock history.
