Steve Winwood was just a teenager when he rocketed into the international spotlight as the prodigious singer of the Spencer Davis Group (which also featured his brother Muff on bass). The blues and R&B-influenced rock of Gimme Some Lovin’ and I’m a Man stood among the leading hits at the peak of the British Invasion, Winwood’s singing drawing comparisons to that of his idol Ray Charles - despite his tender age. 2010 sees the release of the Steve Winwood retrospective box set titled Revolutions.
