Doors open at 5:30, with the Shore Bites food truck and beer, wine, and soft drinks at the FIX Bar. Purcell, 23, a North Carolina native, was “steeped in Appalachian old-time and bluegrass traditions” from an early age and has already made a name for himself in American string band music, said a release. Purcell formed Cane Mill Road as a teenager, and by the time he was 17, the band had performed in 25 states and had seen multiple entries on the Billboard Top 10 Bluegrass charts. In 2019, it was the recipient of the Bluegrass Music Association’s Momentum Band of the Year Award. Tickets are $20 online at flatironcrossroads.com or $25 at the door.
