Now That's Class, our favorite punk rock bar in town, turns 9 today. As can be expected from the club that hosts everything from concerts to skating contests and dodgeball tournaments, the celebration will be unhinged. The club plans to have a mechanical bull in the show space, and patrons can ride the thing (for a fee) from 8 p.m. to midnight. Bands such as Greaves, Miss Macy & the Low Pay Daddys will perform. It all starts at 8 p.m. (Niesel)
