Quiet Riot is an American heavy metal band founded in Los Angeles in 1973 by guitarist Randy Rhoads and bassist Kelly Garni. The original lineup featured Rhoads and Garni with lead vocalist Kevin DuBrow and drummer Drew Forsyth, though that version of the band was mired in turmoil that would eventually see Garni fired for making death threats towards DuBrow. Their most commercially successful lineup consisted of DuBrow alongside guitarist Carlos Cavazo, bassist Rudy Sarzo and drummer Frankie Banali, and in 1983 released their breakthrough album Metal Health, which is known for being the first heavy metal album to top the Billboard album chart. The band had several hit singles which charted on the Billboard Hot 100, including "Cum On Feel the Noize", "Mama Weer All Crazee Now" (both cover songs of the glam rock band Slade), and "Metal Health (Bang Your Head)". The band is ranked at No. 100 on VH1's 100 Greatest Artists of Hard Rock.
