Detonator is the fifth studio album by American glam metal band Ratt, released August 21, 1990, by Atlantic Records. This is the last album to feature bassist Juan Croucier until his return in 2012, as well as guitarist Robbin Crosby before his death in 2002.
Though their previous album Reach for the Sky went platinum, it met with some criticism regarding the quality of their songs. In an attempt to regain the popularity that Ratt had in the mid-1980s, the band parted ways with long-time producer Beau Hill. Songwriter Desmond Child and his personal sound engineer Arthur Payson were hired as producers for the album. The album is notable for featuring Ratt's only power ballad, "Givin' Yourself Away". The band also gravitated towards a more glam metal/pop metal sound on Detonator.
