For all of you folk fanatics and alt country fans, new at Quimby's this week is Pioneers of Country Music, a set of 40 trading cards illustrated by R. Crumb. Brief bios on the back of each card give the histories of Gid Tanner and his Skillet Lickers, Uncle Dan Macon and His Fruit-Jar Drinkers, Al Hopkins and his Buckle Busters and other whimsically named bands. Two earlier series, Early Jazz Greats and Heroes of the Blues, also feature art by R. Crumb.
