Soul music grew out of gospel and rhythm and blues in the late 1950s, and the promotional art that followed it reflected that energy: bold color, expressive lettering, and performers treated as visual subjects worth serious attention. Concert posters from the 1960s and 1970s, when soul crossed over into rock venues and festival circuits, produced some of the most inventive commercial illustration of the era. The period originals here come from that intersection of music and graphic design.
