Isle of Man native Davy Knowles brings his blues-rock to the Castle Theater Friday night (Feb 12). Still just in his late 20's, Knowles says it was his father that first introduced him to the great British and American blues legends, as well other rock music of the 1960's and 70's. Now living in Chicago, Knowles talks with WGLT's Jon Norton about a DVD project that has him back in Isle of Man. He also talks about how his life changed the moment he first heard "Sultans of Swing" by Dire Straits.
