Stephen Lawrence Winwood (born May 12, 1948 in Great Barr, West Midlands) is an English singer-songwriter and multi-instrumentalist who, in addition to his solo career, was a member of the bands the Spencer Davis Group, Traffic, and Blind Faith.
Winwood was a part of the Birmingham rhythm and blues scene from a young age, playing the Hammond B-3 Organ and guitar, backing blues singers like Muddy Waters, John Lee Hooker, T-Bone Walker, Howlin' Wolf, B. B. King, Sonny Boy Williamson II, Eddie Boyd, Otis Spann, Chuck Berry, and Bo Diddley on their United Kingdom tours (the norm at that time being for US singers to travel solo and be backed by 'pick-up' bands).
Winwood became a member of the Spencer Davis Group at 15 with his older brother 'Muff' (who later had much success as a record producer), and had hit singles with "Keep On Runnin'". Steve co-wrote and recorded "Gimme Some Lovin'" and "I'm A Man" before leaving to form Traffic with Chris Wood, Jim Capaldi and Dave Mason.
