Jack Bruce, one of rock's greatest bassists, as well as a powerful lead vocalist and blues harmonica player, died at 71 on Saturday. The Scottish-born Bruce was a member of Cream, the ultimate rock power trio, with Eric Clapton, guitar, and Ginger Baker, drums. Afterward, Bruce continued his career with rock, jazz and fusion groups. At a 2005 Cream reunion above in Royal Albert Hall, London, the group performed "White Room," one of the hits, including "Sunshine of Your Love," that Bruce wrote with poet Pete Brown. The lyrics contain an intimation of mortality: "I'll sleep in this place with the lonely crowd; Lie in the dark where the shadows run from themselves."
