The musicians playing are top of the line, and the Rio is a great venue in which to see and hear these amazing folks. David Rawlings plays a lively guitar, and his vocals with Gillian Welsh were to die for. Brittany Has was a treat, and plays so cleanly but with great energy. The young stand-up bass player was solid, creative within his role, and so musical! And the banjo-mando-2nd fiddle-guitar player Willie rounded them out. Fun, sparkling, well-played music all around. The only negative was the miking that required the musicians to be right on them to be heard, so fiddles and ends of sung lines were lost when they stepped back even a tiny bit.
