BIRDS WITH TEETH Lead singer Jon Davis has described his writing style as doodling until he likes it. That approach is what makes this Charlotte rock outfit's take on indie-punk compelling. Like most young bands, they've had some turnover, but with the release of Birds' second album, Two, slated for June 23, the group's evolution should be fun to watch. Modern Primitives, The ThoughtCriminals and Southside Punx are also on the bill for this birthday party/autism fundraiser. $8-$10. The Milestone.
