Bruce's death was confirmed by his family, who uploaded the following message to the musician's website:
It is with great sadness that we, Jack's family, announce the passing of our beloved Jack: husband, father, granddad, and all round legend. The world of music will be a poorer place without him but he lives on in his music and forever in our hearts.
Bruce founded Cream with guitarist Eric Clapton and drummer Ginger Baker in 1966, with the group's melding of psychedelic rock, jazz and blues propelling them to fame and acclaim during their quick run. Bruce sang lead on classic tracks including "White Room," "I Feel Free" and "Sunshine of Your Love."
Before breaking up in 1968, the band had issued three full-length albums, with swan song Goodbye arriving a few months after disbandment. The band's 1968 effort Wheels of Fire would be the first double album to be certified platinum.
While Cream reunited briefly for performances in 1993 and 2005, Bruce maintained a solo career outside of the band, issuing albums on his own since 1969's Songs for a Tailor. Last spring, he issued Silver Rails, his first studio album in over a decade.
Prior to Cream, Bruce had played bass with London-based outfit Alexis Korner's Blues Inc, which also featured future Rolling Stones drummer Charlie Watts.
