Eric Carmen, the lead singer of the Raspberries has died of unspecified causes at the age of 74.

“It is with tremendous sadness that we share the heartbreaking news of the passing of Eric Carmen,” his wife Amy posted on Carmen’s official website. “Our sweet, loving and talented Eric passed away in his sleep, over the weekend. It brought him great joy to know, that for decades, his music touched so many and will be his lasting legacy.”

Carmen co-formed the power pop pioneers Raspberries in 1970. The group reached the Top 5 with their 1972 hit “Go All the Way”, released four critically acclaimed albums, and broke up in 1975.
