Joe's Garage: Acts I, II & III is a 1979 rock opera by Frank Zappa. The album features Ike Willis as the voice of "Joe", a stereotypical garage ban youth who unwittingly journeys through the miasma of the music business. Zappa provides the voice of the "Central Scrutinizer" character—a mechanical voice which narrates the story and haunts Joe's psyche with McCarthyistic 50s-era discouragement and "scrutiny."
