The word traffic is frequently followed by jam.
For the British rock band Traffic, the musical jam session began in the spring of 1967 at a country cottage in Berkshire, England. As the quartet wrote and rehearsed, member Steve Winwood’s soulful voice and wailing organ could be heard on the radio via “Gimme Some Lovin’ ” and “I’m a Man,” monster hits from his previous band, the Spencer Davis Group.
Now woodshedding with Winwood were guitarist Dave Mason, drummer Jim Capaldi and the horn-blowing Chris Wood. The resulting album, Mr. Fantasy, fit right into a year that saw the release of Sgt. Pepper and the rise of San Francisco psychedelic bands Jefferson Airplane and Grateful Dead.
