When Cream broke up in 1968, it wasn't Eric Clapton who was a surefire bet for solo success. Rather, it was Jack Bruce who had the looks and who cowrote and sang the band's major hits, including "Sunshine of Your Love." But Bruce wanted to be a pioneer, not just a pop star, and he was never content to rest on his laurels. This book traces his life and work, from his formative years in classical music (he composed string quartets at 12) and jazz through his early success with Manfred Mann to the short-lived but endlessly influential Cream era and beyond. It's been an often troubled life -- heroin addiction, management rip-offs, family tragedy, and a failed liver transplant -- all of which he speaks about frankly in this authorized biography, telling a story that is sometimes inspirational, sometimes bleak, but always honest.
