Michael Edward Welsh was an American artist and musician who played bass for several bands, including the rock band Weezer. During Weezer's hiatus, he played with Weezer frontman Rivers Cuomo in the band Homie, during Cuomo's time in Boston. Following original bassist Matt Sharp's departure from Weezer, Welsh joined as bassist and played with them from the time that they unofficially regrouped in 1998 until August 2001, when he experienced mental health problems. Shortly afterwards, he retired from music to focus on his art career. Welsh died from a drug overdose on October 8, 2011.
