Thrash metal band Suicidal Tendencies has announced the death of bassist Tim "Rawbiz" Williams through its Facebook page. His cause of death and age are not known at this time, though according to Ultimate Classic Rock, he claimed to be 25 years old back in 2009.

"It's with complete sadness that we have to announce the passing of bassists Tim "Rawbiz" Williams," the band wrote on its Facebook page earlier today. "Tim played bass for Suicidal Tendencies for almost four years until recently."

"Tim was a monster on bass, running around on stage in the pit, giving his all, even when his body wasn't at it's best," the post continued. "We will always remember him and appreciate all the kind words by those that were touched by his bass playing and him personally."

Williams joined Suicidal Tendencies in 2011 and was the group's ninth bassist, replacing Stephen Bruner. He performed on one track on the band's 2013 album 13, its 12th studio album. In addition to his work with Suicidal Tendencies, Williams was also a prolific session musician and producer, playing bass and drums with prominent R&B acts such as Toni Braxton, Boyz II Men, and Keyshia Cole. In 2009, he appeared on Diddy's reality show Making His Band.

Suicidal Tendencies formed in Venice, California in 1981, fronted by lead vocalist and primary songwriter Mike Muir. Other prominent members of the band over the years have included future Metallica bassist Rob Trujillo and former Mars Volta drummer Thomas Pridgen, who is the band's current drummer.
