The details of Janis Joplin’s story are now legend: how the bluesy Texas girl unleashed her fury on the San Francisco hippie scene with Big Brother & The Holding Company, bowled over Columbia’s Clive Davis at 1967’s Monterey Pop Festival, and became the most galvanizing woman in rock. Kris Kristofferson’s “Me And Bobby McGee” wasn’t a typical Joplin song, but her poignant performance, conveying all the battered weariness she must have felt, was all the more gripping for its posthumous success.
