Episode 171: Founded by an irrepressible enthusiast in his very early twenties, Alligator Records grew into the most authoritative and wide-ranging label chronicling urban blues in the US. That man, Bruce Iglauer, owns and runs the label to this day, having released hundreds of albums on artists such as Albert Collins, Koko Taylor, Roy Buchanan, Lonnie Brooks, Edgar Winter, James Cotten, Curtis Salgado, Marcia Ball, The Holmes Brothers and newest star Shemekia Copeland. The hour features Iglauer in conversation, guest appearances by Copeland and artist Selwyn Birchwood, and selections from the new anthology '50 Years Of Genuine House Rockin' Music.'
