Dave Williams' body is discovered on the band's tour bus...

DAVE WILLIAMS, the lead singer of US rock outfit DROWNING POOL, was found dead on the band’s tour bus yesterday (August 14). He was 30 years old.

A cause of death has not yet been determined.

Drowning Pool had been on tour with Ozzfest when tragedy struck. The rolling hard rock revue had been in Noblesville, Indiana on Tuesday (August 13) and bands were enjoying a day off before resuming in Bristow, Virginia tonight. The Ozzfest show will go ahead as scheduled, sonicnet reports.

Drowning Pool rose to fame on the back of success on last year’s Ozzfest. They began the tour opening on the third stage and finished it with slot on the second. They were a Main Stage band this year.

Disturbed frontman David Draiman, a friend of the band, was one of the first people to pay tribute to Williams.

“He was the sweetest man you’ll ever come across in your life,” he said. “[He] didn’t have a bad bone in his body, just very kind-hearted, very good-natured, very genuine, always trying to make everyone around him smile. [He was] always trying to bring some life to the party with his own little dramatic flair.

“Everyone loved him. I don’t know a single person that has ever met Dave Williams and not just instantly fallen in love with him. He could charm anyone to death. He was a very special guy. It’s shocking.”
