Tim 'Rawbiz' Williams, a prolific session bassist, drummer and producer whose recent work included playing bass in Suicidal Tendencies, has died.

The band announced Williams' death with a post on its Facebook page, writing, "It's with complete sadness that we have to announce the passing of bassist Tim 'Rawbiz' Williams. 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 its best. We will always remember him and appreciate all the kind words by those that were touched by his bass playing and him personally."

Neither Williams age nor his cause of death were given, although in a blog he published in 2009, he wrote that he was 25. At the time, he was working to lose weight, and ultimately dropped roughly 200 pounds, an experience partially documented through his appearance on the Puff Daddy VH1 reality series 'Making His Band.'

A 2004 graduate of the Berklee College of Music, Williams went on to work for a list of artists that includes Toni Braxton, Boyz II Men, and Keyshia Cole. He joined Suicidal Tendencies in time to appear on the group's 2013 album, '13,' which ended a 13-year drought of new original material from the band.
