Quiet Riot is marking a moment of silence for its fallen frontman.
Kevin DuBrow, the zebra-pantsed singer for the hit-making heavy metalheads, was found dead in his home in Las Vegas Sunday. He was 52.
News of DuBrow's death was announced on Riot drummer Frankie Banali's Website.
"I can't even find words to say," he wrote. "Please respect my privacy as I mourn the passing and honor the memory of my dearest friend, Kevin DuBrow."
Police and paramedics were alerted by a concerned neighbor Sunday afternoon.
"We got a call to do a welfare check," a Las Vegas Metro Police spokeswoman told E! Online, adding that there were no signs of foul play.
The rocker was pronounced dead at approximately 5:20 p.m.
The cause of death has not been announced. The Clark County coroner will conduct an autopsy and toxicology tests this week, but the official results won't be known for several weeks.
In a statement posted online, Quiet Riot bassist Kelly Garni asked fans to reserve judgment until the coroner issues a report.
"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," Garni wrote on a tribute Website dedicated to Riot cofounder Randy Rhoads.
"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. I will explain to everyone here the facts and the truth in the next 24 to 48 hours as I realize this will affect us all. So please, until then be patient."
According to MTV.com, DuBrow appeared to be in good health and was in New Orleans just before Halloween to celebrate his birthday.
With DuBrow on vocals, Quiet Riot became the first hair metal band to score a Top 5 hit with its cover of Slade's "Cum On Feel the Noize" off the monster 1983 LP Metal Health, thanks to heavy video airplay on MTV. The album itself made history as the first metal release to top the Billboard album charts, supplanting the Police's Synchronicity.
Quiet Riot was formed by Rhoads and Garni in the mid-1970s, with DuBrow and drummer Drew Forsyth. The band broke up when Rhoads left to play guitar for Ozzy Osbourne in 1979. After Rhoads died in a 1982 plane crash, DuBrow relaunched Quiet Riot without any of the founding members.
The rebooted band reached its zenith with Metal Health, which sold 6 million copies and spawned the Top 40 singles "Slick Black Cadillac" and "Metal Health (Bang Your Head)."
While the follow-up Condition Critical was certified platinum and scored two hit singles, "Party All Night" and another Slade cover, "Mama Weer All Crazee Now," the band was eclipsed by other hair bands.
After a succession of lineup changes, Quiet Riot disbanded again in 1989, with the other members actually firing DuBrow after the end of a tour.
The metal mavens reunited in the mid-'90s and continued to play the club circuit. After a brief breakup in 2003, DuBrow issued the 2004 solo album In for the Kill, before the band once again reformed for a 2005 tour with Cinderella, Ratt and Firehouse.
In October 2006, the band released its final studio album with DuBrow, Rehab, on Chavis Records.
"As I mourn his death with a heavy heart, I will remember hearing his voice and the music for the very first time on the radio back in 1983," said label boss Bill Chavis. "I will remember all the great music Kevin and Quiet Riot gave to so many of us over the years, and I will say, 'Thank you, Kevin. May you rest in peace.' "
Funeral plans have not yet been finalized.
