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."
René Berg René Berg (born Ian Bruce, 24 February 1956 – 28 July 2003) was an English musician, vocalist, guitarist, and songwriter, who recorded and performed in a number of bands starting in the late 1970s until his death. His bands included Idle Flowers, Soho Vultures, René Berg Band, along with appearances in Hanoi Rocks, Herman Brood Band, and Jim Penfold's The Killers (1986) (previously known as The Hollywood Killers).
