This isn’t just a cool/fun show, it’s a cool/fun game show! If you haven’t attended one of these, all you need to know is that Grudge Rock is the rock ’n’ roll version of Family Feud. Host Jake Stratton pits two of the best local bands against each other—in this case, pop/punk perfectionists Wimps will face melodic/dreamy experts Posse in this music trivia battle—and the winner takes home the door money! All of it! But the loser gets fabulous consolation prizes, so it’s a win-win—a win-win-win if you throw the bands’ live performances into the equation. (Highline, 210 Broadway E,, 9 pm, $8, 21+)
