Dave Matthews Band trekked across the U.S. on a late-summer 2007 U.S. tour that touched down at the Verizon Wireless Amphitheatre in Charlotte, Va., on Sept. 19. The trek also included a Sept. 6 concert at nearby Virginia Tech in memory of the victims of the mass shooting that took place there earlier that year -- perhaps inspiring the heart theme featured on many of the posters from the tour.
