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