CMJ Music Marathon. British singer Dan Black, formerly of the band the Servant, has worked with Kid Cudi and played Lollapalooza. In England, he is identified with something called "wonky pop," a term that—please, dear God—will never enter the American lexicon. Fans of Donna Summer and Goldfrapp will dig local supporting electro gang the Golden Filter, and then there's joke-of-a-band Boy Crisis, featuring one Victor Vazquez (also of party-rap clowns Das Racist). Safe to say, tonight will get messy.
