It doesn't have a line down the block or a slate of superstar celebrity guest DJs. It's not the place to see or be seen. Nor is it filled with fickle hipsters who instantly think everything is so ten minutes ago. What Chit Chat is, is the city's best house party -- er, make that club night. Helmed by Jason Heller and Big Al, the dynamic duo who created the wildly popular and now-defunct Off the Wall series at the hi-dive, Chit Chat has a casual, unassuming vibe unlike any other night in town. Every Saturday, the DJs keep the Old Curtis St.'s dance floor jumping as they take turns behind the decks, spinning 45s (you know, those old-fashioned black plastic things with the holes in the middle?) from their personal collections, including the deepest classic soul cuts you've never heard. You think you know vintage soul? You don't know Chit.
