Every single Grateful Dead concert, 2,300+ live shows over 30 years, has an archived recording except one — March 17th, 1970 at Kleinhans Music Hall in Buffalo, NY. There is a reward for its discovery.

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.
