One of his most popular and infamous albums, Sheik Yerbouti finds Frank Zappa unleashing his unique brand of sociological documentation on the disco-injected culture of the late '70s. From crises of sexual identity to the rhythmically challenged, the songs are hilarious and occasionally close to home (The Anti-Defamation League of B'nai B'rith didn't care much for "Jewish Princess"). The satire is some of Zappa's most scathing and unsympathetic, and the music is equally loud and unrelenting--especially when showcasing the talents of sidemen Terry Bozzio and Adrian Belew. A must-have in any Zappa collection. --Andrew Boscardin
