Dave Matthews and Tim Reynolds will be playing an acoustic concert at the downtown amphitheater, Red Light Management announced in a press release this morning. The performance will be on Saturday, August 20. All proceeds will support charities, via an online service that allows ticket buyers to direct their payment to nearly any 501(c)3 in the country. The duo last performed together in Charlottesville at the Jefferson Theater in 1994. Tickets go on sale at 10 AM on August 5th, via the amphitheater’s website.
