John Warren Geils Jr., better known as guitarist J. Geils of the J. Geils Band, was found unresponsive at his Groton, Massachusetts, home on April 11th; police later determined that he had died of natural causes. He was 71.
"Thinking of all the times we kicked it high and rocked down the house! R.I.P. Jay Geils," vocalist Peter Wolf wrote in a post to Facebook shortly afterward.
