Quiet Riot is an american heavy metal band, whose 1983 & 1984 success paved the way for the glam metal scene's commercial success in the mid 80's. They are best known for their cover of Slade's hit "Cum on Feel the Noize."

They were founded in 1975 by guitarist Randy Rhoads with the original lineup featuring Kevin DuBrow (vocals), Kelly Garni (bass) and Drew Forsyth (drums). After failing to break out of the Los Angeles metal scene with a record contract (unlike their contemporaries Van Halen), the band eventually scored a deal with Columbia Records s second single "Cum on Feel the Noise" (a remake of one of Slade's big U.K. hit from 1973) was released; it spent two weeks at #5 on the chart. It was the first heavy metal song to make the Top 5 on Billboard Magazine's "Hot 100 singles chart" and it was the first of a string of Slade sound-alikes recorded by the group. The band were relunctant to record the song, as none of them were Slade fans, and recorded it in one take, trying to play their worst. The success of the single helped carry "Metal Health" to the top of Billboard Music Charts pop album charts, making it the first heavy metal album to ever reach #1.

A #1 album and a top 5 single was unheard of for a heavy metal band in 1983. The "Metal Health" album also displaced Michael Jackson's "Thriller" album from #1. "Metal Health" paved the way for a new, stronger commercial viability for heavy metal.

The group's follow-up, "Condition Critical," was a relative disappointment critically and commercially, selling only 3 million units. This release included yet another Slade cover (the single, "Mama Weer All Crazee Now" - a UK chart topper for Slade) and numerous musical and lyrical nods to the aforementioned act; whether this was a decision made the band or their producer is still subject to debate as evidenced in their VH1 "Behind The Music" documentary.

This led to Sarzo quitting the group in 1985. The bass slot in Quiet Riot was filled by Chuck Wright. Next, the band released "QRIII" in 1986, another commercial failure. Fed up with DuBrow's antics, the rest of Quiet Riot fired him from his own band and replaced him with former Rough Cutt vocalist Paul Shortino. Wright was also fired and was replaced by Sean McNabb. The band released "Quiet Riot" in 1988, which was another failure. This 1988 album technically has the same name as their original first album with Randy Rhoads. The band fell apart after a tour that ended in Hawaii in 1989 and DuBrow fought to keep control of the name.

By 1991, tempers had cooled enough for the former bandmates to communicate. DuBrow and Cavazo formed Heat, but eventually switched to Quiet Riot again and released "Terrified" (1993) with Banali and Kenny Hillery (bass). That same year DuBrow released "the Randy Rhoads Years" featuring tracks from Quiet Riot's Columbia albums and some previously unreleased material (many of which featured newly recorded vocals). Hillary left in 1995 and committed suicide on June 5, 1996; Wright rejoined Quiet Riot to play bass. The band released "Down to the Bone" that same year. The following year (1996), the band released a "Greatest Hits" album, which included nothing from the original two Rhoads albums and nothing from the two 90's albums, but did have a few tracks from the 1988 Shortino album. After that, Rudy Sarzo joined up again in 1997, and the band began touring.

The tour was not successful, and the band was arrested several times; one angry fan sued DuBrow for injuries sustained during a show. The group still managed to release "Alive and Well" in 1999 which featured new songs and several rerecorded hits. They followed this up with "Guilty Pleasures" in 2001.

Quiet Riot officially broke up in February 2003, and Sarzo joined Dio in the following year. However, they reunited in 2005 with the line-up being made up of DuBrow, Banali, Wright, and guitarist Alex Grossi. The band joined the Rock Never Stops Tour in 2005 with Cinderella, Ratt, and Firehouse.
