Former Weezer bassist Mikey Welsh was found dead in his Chicago hotel room this weekend. He was only 40 years old. I've read reports that drugs might have been a factor but I really hope not. Welsh joined Weezer v2.0 in 1998, replacing original bass player Matt Sharp, played on the band's second self-titled album (aka The Green Album) that resurrected their career and then abruptly left the band in 2001 after suffering a nervous breakdown. He left the music business for good, spending the last decade reinventing himself as an artist and family man. R.I.P. sir.
