It was the Monterrey Pop Festival that put Big Brother and the Holding Company on the road to stardom. Their “Cheap Thrills” album, their last with Janis Joplin as a member, originally was to feature the group naked in bed on the cover. But the record company objected. Instead the cover was drawn by artist Robert Crumb. Released by Columbia Records in 1968, a stereo copy is worth up to $100 while a mono copy can get you up to $500.00 today.
