It's true that folk music, real, folksy folk music in the tradition of Kate and Anna McGarrigle, never actually died, but it took the Wailin' Jennys to get it off life support. Brilliant three-part harmonies combine with rich guitar phrasing on their debut full-length, 40 Days (Red House), and their live shows are rumored to be vivacious and thoroughly enriching. See them Friday, July 29, at the Rio Grande Zoo, as part of the "Summer Nights" concert series and Friday, July 30, at their AMP House Concert.
