Query: Great set of down-home bluegrass tunes

This is a great set of bluegrass from Galax, Virginia banjoist Stevie Barr, of the band No Speed Limit. Mixes secular and gospel material, as well as informal live performances with several utterly amazing studio tracks, particularly the instrumentals where Barr really cuts loose on the banjo... And, man, is he good! Very fast, and very good. Has a nice DIY feel that festival goers and back-porch pickers will appreciate. This is the real deal. (DJ Joe Sixpack)
