Two hours away in Davenport, Iowa, a group of about a dozen "working class" performers from around the country performed for a packed house of about 2,400 people at the historic Alder Theater Friday night. The campaign said the timing of the two competing concerts was a coincidence. As one of the organizers, Scott Goldstein put it: “There is a long lineage of progressive, working class musicians” and their show was all about that tradition. “You can’t separate politics and music. I can’t,” singer-songwriter Wayne Kramer told ABC News. “Everything that we do is political.” Kramer, who is best known for the 1970s band Motor City 5, pulled no punches when asked about the difference between the two concerts. “One is a manufactured, celebrity-driven, show business and the other is the real rock,” he said. “Tonight - this isn’t a question of celebrity, it is a question of sincerity.”
