Freak Out! is the debut record by the American rock band the Mothers of Invention, released June 27, 1966 on Verve Records. Often cited as one of rock music's first concept albums, the album is a satirical expression of frontman Frank Zappa's perception of American pop culture and the nascent freak scene of Los Angeles. It was also one of the earliest double albums in rock music, and the first two-record debut album. In the UK, the album was originally released as an edited single disc.
