In case you have no plans tonight and you find yourself in or adjacent to the Red Hook area of Brooklyn, N.Y.: I will be performing at the Jalopy Theater (315 Columbia St.) tonight as part of “Critical Karaoke,” in which music scribes perform a piece that’s written to the length of the song they’re writing about; also on the bill are Michaelangelo Matos, Robert Christgau, Rob Sheffield, Rob Harvilla, among others. The song I’m going to discuss is by an act that’s a frequent topic of conversation around these parts, although it’s probably not the act you’re thinking of right now. Showtime’s 9 p.m. Come down! (I’ll post the piece tomorrow, for those of you who are geographically challenged.) [Jalopy Theater]
