(PUNK-ROCK BLUEGRASS) I first saw the Meat Purveyors five years ago in a ramshackle house in Chicago's warehouse district that had been converted into an urban juke joint. The band was smart and funny, banged the holy hell out of their instruments (guitar, mandolin, standup bass), played originals and covers (ABBA, Ratt, Bill Monroe), and drank (beer, whiskey). I fell in love. Tonight is your last chance to see them—it's their second-to-last show. Don't miss it. (Tractor Tavern, 5213 Ballard Ave NW, 789-3599. 9 pm, $13.)
