The wife of Michael Davis, the bassist of influential late 1960s rock band MC5, says the musician has died of liver failure. He was 68.

Angela Davis said Saturday her husband died at Enloe Medical Center in Chico, Calif., on Friday afternoon after being in the hospital almost a month battling liver disease.

The bassist gained attention in the revolutionary Detroit band MC5 and later played in a version of the group called DKT-MC5 with former MC5 members Wayne Kramer and Dennis Thompson.

Michael Davis injured his back in a motorcycle accident in 2006, and afterwards co-founded the non-profit Music Is Revolution Foundation, dedicated to supporting music education in public schools.

Davis is survived by his wife, their three sons and a daughter from a previous marriage. His wife says a funeral has not been planned at this time.
