Colorado is known for snow, not sand, but this quintessential country-chill band will make you dream of the beach and the surf. The Zac Brown Band's Southern-twang-meets-Caribbean-ease sound longs for summer nights and good beer. The group's 2012 release, Uncaged, soared to number one on the Billboard 200 chart. In the open air of Red Rocks, expect to hear favorites like "Toes" and "Colder Weather" along with new tracks. Wed-Fri 7 p.m.
