Here's what looks to be the Americana-type roadshow of the summer: The "Big Surprise Tour," Aug. 10 at Cary's Booth Amphitheatre with Old Crow Medicine Show, Dave Rawlings Machine (featuring Gillian Welch, of course), Felice Brothers and Justin Townes Earle (whose dad plays Wednesday in Carrboro).
The show's format calls for two 90-minute sets, with lots of cameos, collaborations and sitting in among all four acts. Tickets go on sale Friday at 10 a.m.
