The HeadCount team was in fluid motion this past weekend at Bonnaroo. On Friday night some festivalgoers in Centeroo were met by a clipboard toting Michael Kang who walked around the site registering voters. Over the course of the weekend, HeadCount invited a number of artists to record public service announcements which will air on TNT, TBS and other stations encouraging individuals to register and vote. The list of musicians who recorded PSAs includes Dave Matthews, Michael Kang, Jeff Tweedy, Sam Bush, Al Schnier, Rob Mercurio and Rich Vogel.
