This multi-talented West Midlands group gained international success in the late 1960s and early 1970s, particularly in the USA where as a three piece they attracted a huge following. In Britain, they are remembered mostly for some memorable and ground-breaking singles and albums that scored high chart placings.

Traffic was formed when Steve Winwood, who was the focal point of the Spencer Davis Group decided to move beyond the restrictions of the group and form a band with three other Birmingham area musicians. Jim Capaldi had formed his first band at the age of fourteen and was soon recording for Pye records with the Hellions. Shortly thereafter, he was gathering rave reviews in a band called Deep Feeling which he shared with fellow Traffic founder Dave Mason & Family founding member Poli Palmer. The band played rock & blues and locally were in a league of their own.

Traffic is dead, but the corpse is lively. Though Steve Winwood has split to find his own way, the rest of Traffic is carrying on with a new name, a returnee from Traffic past, and a new member. New name is "Mason, Capaldi, Wood & Frog," reflecting the new lineup: Dave Mason, bass and vocals; Jim Capaldi, drums and vocals; Chris Wood, reeds; and Mick Weaver, leader of the Wynder K. Frog band, on organ, in place of Winwood.
