Ratt is an American glam metal group formed in Los Angeles, CA and initially featured Stephen Pearcy (vocals), Robbin Crosby (guitar), Warren DeMartini (guitar), Juan Croucier (bass), and Bobby 'The Blotz' Blotzer (drums). They evolved out of 70s band Mickey Ratt, transforming into their present form in 1983, and embraced the Sunset Strip blend of pop hooks mixed with aggressive rock. Hitting a slick sound similar to the power pop of Cheap Trick as well as the metal of Iron Maiden, the band is best known for the multi-platinum album smashes 'Out of the Cellar' and 'Invasion of Your Privacy'.
