The British singer and bass player Jack Bruce has died at the age of 71 from liver disease. Bruce formed the influential rock band Cream in the 60s with guitarist Eric Clapton and was the voice and songwriter behind classic tracks like “Sunshine of Your Love,” and “I feel free.” He was born in Glasgow, and began playing bass as a teenager. He dropped out of music school when he was not allowed to play jazz. Cream split in November 1968 having sold 35 million albums in just over two years. After Cream, Bruce played with top jazz musicians including drummer Tony Williams and guitarist John McLaughlin as well as with rock stars like Lou Reed and Frank Zappa.
