Invisible Children, an awesome non-profit (from San Diego!) that provides education and economic relief to war-torn Uganda, has enlisted big-name emo/punk musicians to raise awareness for the cause. Members of Thrice, Saves the Day, Sparta and Switchfoot will perform acoustic sets as well as auction off drum kits and hand-painted guitars. All the positive action goes down December 19th at the legendary Troubadour club. Tickets available here.
