Out of sympathy, fans ought to bang their heads instead of bowing them: Quiet Riot singer Kevin DuBrow was found dead in his Las Vegas home on Sunday, according to the band's drummer.

Frankie Banali announced DuBrow's death on his official website. "I can't even find words to say. Please respect my privacy as I mourn the passing and honor the memory of my dearest friend ..." Banali wrote.

DuBrow celebrated his 52nd birthday last month in New Orleans and appeared to be in good health, according to a report on MTV.com. No cause of death has been determined.

One of the founding members of the 80s' heavy metal glam rock scene, Quiet Riot was actually formed back in the early 70s by Randy Rhoads and Kelly Garni, with DuBrow handling vocals. Their breakthrough album -- Metal Health -- was released in March 1983. It became the first heavy metal album to debut at No. 1 on the music charts and featured the hit songs "Cum On Feel The Noise" and "Metal Health."

DuBrow stood out among his heavy-metal peers for his gravely, loud voice and the suspenders he often wore on stage. In videos and promotional photos, DuBrow often donned a straightjacket and metal mask over his face. 

According to the Associated Press, a neighbor summoned paramedics Sunday to DuBrow's home, where he was pronounced dead at 5:20 p.m. Police told the AP that there was no forced entry at the house. Toxicology tests have been performed, and authorities await the results.

"Out of respect for both Kevin and his family, I won't comment further," Banali told CNN. "There's going to be a lot of speculation out there, and I won't add to that. I love him too much."

Quiet Riot's last studio album was "Rehab" in 2006. Click here to see Quiet Riot's video for "Cum On Feel The Noise."
