The first rock and roll power trio Cream (Eric Clapton, Jack Bruce and Ginger Baker) started their first tour today back in 1966, with a concert in Manchester, England. The band had their first public performance at the Windsor Festival prior to hitting the road. Cream fans got into the great combination of high-volume blues jamming, extended solos and flashy instrumental showmanship.

Here's a more subdued Cream appearing on British TV from the same time period.
