Minnesota folk band Dark, Dark, Dark is touring in support of a new CD, Wild Go, which contains a single, “Daydreaming,” that was featured in Episode 7, Season 7 of "Grey’s Anatomy," demonstrating again that the path to musical success lies in television. With an instrumental collection that includes piano, accordion, trumpet, clarinet, banjo, drums and bass plus vocals, Dark, Dark, Dark seems likely to provide a musical show that is more revue than concert, more varied than stylistically focused and perhaps even more interesting than anything else. Bro. Stephen opens. Uncle Slayton[s, May 20. Tickets are $8 adv/$10 DoS.
