Aretha Franklin, the “Queen of Soul,” is known for inspiring awe, motivating listeners to dance, and — on at least one occasion in Colorado — sparking a riot. On Aug. 4, 1968, Franklin was scheduled to perform a Sunday night concert at Red Rocks Amphitheatre. But she went on stage to announce that she would not be performing because she hadn’t been paid by the program’s impresario, according to Denver Post archives. About 200 people in the audience stormed the stage, destroying chairs, music stands, a grand piano, footlights, electronic equipment and anything else they could get their hands on.
