Kevin DuBrow, the voice and face of Quiet Riot throughout the glam metal band's turbulent history, was found dead Sunday at his home in Las Vegas. He was 52.

The exact cause of DuBrow's death was unknown pending an autopsy, a spokesperson for the Clark County Coroner's Office told the Associated Press.

"I can't even find the words to say," Quiet Riot drummer Frankie Banali wrote on his Web site. "Please respect my privacy as I mourn the passing and honor the memory of my dearest friend, Kevin DuBrow."

In a post on a Web site honoring founding Quiet Riot guitarist Randy Rhoads, the band's bassist, Kelly Garni, urged patience about details on the singer's death.

"I ask this to all of you not only for myself but for other friends and family," Garni wrote. "I ask that no one here offer any speculation or opinions, theories or other things that could be construed as negative or, and I'm sorry for this, even sympathetic, right at this immediate time. I am already, within hours of this, having to deal with untrue rumors and speculation and that only adds fuel to that. There is a tendency for the subject of Kevin to incite flames on every board, and now is not the time for that."

DuBrow founded Quiet Riot in the mid-1970s along with acclaimed guitarist Randy Rhoads, who later became Ozzy Osbourne's guitarist and died in a plane crash in 1982.

Rhoads' departure sparked a number of changes in the band in the late 1970s, but Quiet Riot caught fire with their smash 1983 album Metal Health, propelled by a cover of UK band Slade's "Cum on Feel the Noize." The song's video was featured in heavy rotation on a then-fledgling MTV, and Metal Health sold more than 6 million copies.

Quiet Riot's follow-up albums did not sell nearly as well, and DuBrow was essentially fired from the band amid the ensuing rancor. DuBrow regrouped Quiet Riot in the 1990s and the band has since played sporadically. The band's last album, Rehab, hit stores in October 2006.
