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 Simcock Jack Simcock (6 June 1929-13 May 2012) was a British painter. He was born to a mining family in Biddulph, Staffordshire and studied at Burslem School of Art. He is best known for "a long series of bleak, sombre oils on board" of the Mow Cop area in which he lived for much of his life. Reginald Haggar highlighted the "richness of colour that underlies the seemingly black and white effects, glints of terracotta and old gold through steely grey" in a "Sentinel" article of 1963.
