Los Angeles thrash metal outfit Suicidal Tendencies have announced the death of bassist Tim "Rawbiz" Williams, a prolific musician who -- in addition to playing with Suicidal Tendencies since 2011 -- worked with everyone from Toni Braxton to Boyz II Men to Keyshia Cole.

"It’s with complete sadness that we have to announce the passing of bassist Tim “Rawbiz” Williams," the band wrote on Facebook. "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. We will always remember him and appreciate all the kind words by those that were touched by his bass playing and him personally."

Williams also appeared on Diddy's 2009 reality show Making His Band, which documented the hip-hop mogul's search for his backing band.

Neither Williams' cause of death nor his age are known at this time.
