The Avett Brothers at Red Rocks this summer with Grace Potter & the Nocturnals

Mark your calendars: We've just heard that the Avett Brothers are due at Red Rocks on Saturday, July 9, with Grace Potter & the Nocturnals. Presale begins on Tuesday, March 8. Tickets officially on sale next Saturday. Don't snooze. How quickly do you think that bad boy is going to sell out? Um, given their recent exposure on the Grammys and their rapidly growing fan base in Colorado, we're going to go with "almost immediately" for a $100, Alex.
