David Clayton-Thomas, the lead singer of Blood, Sweat & Tears and songwriter behind hits such as “Spinning Wheel,” has died. He was 84.

The musician’s publicist shared with Billboard on Thursday (June 25) that he had passed away peacefully the evening prior at St. Michael’s Hospital in Toronto. No cause of death was provided, but the rep did add that a memorial benefit concert will soon be held in Clayton-Thomas’ honor supporting Peacebuilders Canada, an organization that promotes restorative justice for youth, which he championed for years up until he died.
