Juan Croucier

Juan Croucier (born August 22, 1959, in Santiago de Las Vegas, Cuba) is a Cuban-American heavy metal musician.


Croucier attended Torrance High School in Torrance, California. He played bass in Dokken with guitarist/vocalist Don Dokken and drummer Bobby Blotzer. Blotzer and Croucier left Dokken in 1978 to form FireFoxx along with Ron Abrams on guitar.[1] Croucier served as bassist for Ratt during the 1980s, and was also very briefly in Quiet Riot and DuBrow. Reportedly, Croucier played with Quiet Riot shortly before Randy Rhoads left to play with Ozzy Osbourne and played with DuBrow in 1981 but did not record with either.

Croucier played with Dokken for about four years and toured Germany with the band several times. He was a member of both Ratt and Dokken simultaneously for approximately 18 months before leaving Dokken. He played and sang backup on Dokken’s Breaking the Chains album, and co-wrote two songs. His replacement, Jeff Pilson, appears in the videos from the album.

With Ratt, Croucier wrote many of the band’s biggest hits such as “Lack of Communication” and “You’re in Love”. His backing vocals also became a trademark part of Ratt’s sound.

Croucier went on to own and operate a recording studio in Los Angeles called “The Cellar” where he recorded, produced and engineered hundreds of records for various bands and solo artists. He also formed a new band, Liquid Sunday a project based on his solo album of the same name.

Liquid Sunday played on the same bill for one show with Pearcy during the summer of 2006 and later formed a new band called Dirty Rats, consisting of Croucier on bass and lead vocals, Carlos Cavazo on guitar, and John Medina on drums. Carlos Cavazo left Dirty Rats to join Ratt, but later returned to Dirty Rats.

Reportedly, the current line-up going by the name Dirty Rats features completely different musicians, except for Juan Croucier. Including guitarist from the band Love/Hate Jon E. Love and drummer from band Black and Blue Pete Holmes.

On May 12, 2012, Croucier reunited with RATT and performed with the band at the M3 Rock Festival for the first time since 1991.
