John Symon Asher “Jack” Bruce (14 May 1943 – 25 October 2014) was a Scottish musician, singer and songwriter known primarily for his contributions to the British supergroup Cream, which also included the guitarist-singer Eric Clapton and the drummer Ginger Baker. In March 2011 Rolling Stone readers selected him as the eighth greatest bass guitarist of all time. “Most musicians would have a very hard time distinguishing themselves if they wound up in a band with Eric Clapton and Ginger Baker,” the magazine said at the time, “but Jack Bruce was so gifted on the bass that he did it with ease.”

Bruce maintained a solo career that spanned several decades and also played in several musical groups. Although recognized first and foremost as a vocalist, bassist and songwriter, he also played double bass, harmonica, piano, cello and guitar. He was trained as a classical cellist and considered himself a jazz musician, although much of his catalogue of compositions and recordings tended toward rock and blues.
