This quality embroidered hat features Chance Records and Chicago, Illinois. Chance Records was a Chicago-based blues label that captured the raw, postwar electric blues sound coming out of the city in the 1950s. It’s closely associated with influential Chicago blues artists and represents a pivotal moment when the blues moved from Southern roots to an urban, electrified edge.
