Mikey Welsh the ex-Weezer bassist has passed away at just 40 years old. The cause has yet to be determined.

On the Weezer website the band have this to say in tribute:
"It saddens me and the guys in Weezer so much to say that our beautiful, creative, hilarious and sweet friend Mikey Welsh has passed away at the very young age of 40. A unique talent, a deeply loving friend and father, and a great artist is gone, but we will never forget him. His chapter in the weezer story ('98 - '01) was vital, essential, wild, and amazing.

Mikey was never one to shy away from the absurd, dangerous or strange, and he did so with a gusto few others had. No one had quite the stage presence of Mikey, nor have there been many who pulled the types of shenanigans he did at shows. If it rocked, he had to try it - and he always found a way to pull it off. "

We at Roomthirteen would like to pass on our condolences to his family and friends.
