Mikey was an interesting guy. He took over for original bassist Matt Sharpe and stayed with Weezer for a couple of years before suffering a nervous breakdown which he blamed on drugs, touring fatigue and a few unspecified things.
He left the band, got his act together and then launched a successful second career as a painter with his wife and kids in Burlington, Vermont.
He was staying at the Raffaello Hotel in Chicago, When he didn’t meet his 1pm check-out time, hotel staff when to his room where he was found unconcious and not breathing. He was pronounced dead a short time later. No cause of death was immediately apparent, although a drug overdose is suspected. The Cook County Coroner’s Office says they should have results by sometime Sunday afternoon.
Mikey Welsh was 40.
UPDATE: In a super-freaky bit of prescience, Mikey tweeted this on September 26th.
