Cheap Thrills, the major-label debut of Janis Joplin, was one of the most eagerly anticipated, and one of the most successful, albums of 1968. Joplin and Big Brother had earned extensive press notice ever since they played the Monterey Pop Festival in June 1967, but their only recorded work was a poorly produced, self-titled Mainstream album, and they spent a year getting out of their contract with Mainstream in order to sign with Columbia while demand built. When Cheap Thrills appeared in August 1968, it shot into the charts, reaching number one and going gold within a couple of months, and "Piece of My Heart" became a Top 40 hit. Joplin, with her ear- (and vocal cord-) shredding voice, was the obvious standout. Nobody had ever heard singing as emotional, as desperate, as determined, as loud as Joplin's, and Cheap Thrills was her greatest moment. Big Brother's backup, typical of the guitar-dominated sound of San Francisco psychedelia, made up in enthusiasm what it lacked in precision. But everybody knew who the real star was, and Joplin played her last gig with Big Brother while the album was still on top of the charts. Neither she nor the band would ever equal it. Heard today, Cheap Thrills is a musical time capsule and remains a showcase for one of rock's most distinctive singers.
