Kevin Mark DuBrow (October 29, 1955 – November 19, 2007) was an American singer, best known as the lead vocalist of the heavy metal band Quiet Riot from 1975 until 1987, and again from 1993 until his death in 2007.

[2] By the time he was in his mid-teens, he had developed an appreciation for a number of British rock acts including the Small Faces, Queen, Spooky Tooth, Rod Stewart and Humble Pie.

"[4] Quiet Riot was formed by Randy Rhoads and bassist Kelly Garni (who would later be replaced by Rudy Sarzo) in 1975, who recruited DuBrow and drummer Drew Forsyth.

For a time the band's name was changed to DuBrow, which had a rotating lineup of members including Leon, Chuck Wright, Frankie Banali, with brothers Tony and Carlos Cavazo.

After the death of Rhoads in a plane crash in 1982, while on tour with Osbourne, DuBrow changed the name of the band back to Quiet Riot.

Rudy Sarzo, who had also joined Ozzy Osbourne, left Osbourne's band and rejoined Quiet Riot shortly before the release of Metal Health, which went to the top of the charts, making Quiet Riot the first metal band to achieve number one status on their (U.S. release) debut album.

Their singles included "Cum on Feel the Noize" (originally written and recorded by English band Slade in 1973), and "Metal Health (Bang Your Head)".

But it took the band to make the change.” However, DuBrow had a habit of publicly bad-mouthing other bands, which alienated a lot of musicians and fans, and also caused problems for Quiet Riot members (bassist Rudy Sarzo was famously punched in the face by Ozzy Osbourne after DuBrow publicly insulted the English singer).

“We all indulged," said Banali, "but Kevin could be told nothing by no one, and his lifestyle choices had made it impossible for us to continue with him.” [7] Shortly after his firing from Quiet Riot, DuBrow signed with Kim Richards for personal management.

DuBrow dated Las Vegas radio DJ Lark Williams for seven years, breaking up shortly before his death.
