Jack Bruce and Buster Bloodvessel are both singers or painters?
Jack Bruce 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 guitarist-singer Eric Clapton and 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."
Jack Noren Jack Noren (October 19, 1929, Chicago - March 17, 1990, Chicago) was a jazz drummer and vocalist born in America but best known for his work in Sweden.
