Sad news to report from Suicidal Tendencies. Former bassist Tim 'Rawbiz' Williams has passed away.

Williams joined Suicidal Tendencies to man the low end after the departure of longtime bassist Stephen Bruner. During his near four-year run with the legendary crossover thrash band, Williams performed live and lent his talents to one track on Suicidal's most recent album, '13.'

Suicidal Tendencies revealed the sad news via Facebook early this morning (Aug. 27):

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 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.

We'd like to send our thoughts and best wishes to the family and friends of Tim 'Rawbiz' Williams. Watch the bassist in action live with Suicidal Tendencies below.
