About Juan Croucier
Juan Croucier is a Cuban-born American musician. He is best known as the bassist for the hard rock/glam metal band Ratt. Croucier played with Quiet Riot shortly before Randy Rhoads left to play with Ozzy Osbourne, and played with DuBrow in 1981, although he did not record with either. They went on to form a new version of Quiet Riot, resulting in the debut record Metal Health. Croucier wrote many of Ratt's biggest hits such as "Lack of Communication" and "You're in Love," and his backing vocals became a trademark part of the band's sound.
