THE WINTER SOUNDS Not too long ago, this Nashville quintet went to Chicago and played a swanky company Christmas party, recorded a Daytrotter session, and played sets at Martyr’s and for a local high school choir class. Which is actually a neat summation of the music — it’s just exotic enough to sound like that one Decembrists’ record the suits get along with; it’s rooted in enough folk tradition to sound good pared down live in the studio; it’s just Portlandia enough for the indie bar crowd; and it’s just glockenspiel-friendly enough to reveal its high school band-grad roots and Polyphonic Spree fan-club membership past. None of that, by the way, is meant as insult. With Secret Hospital, Andy D (not the Doorbum, btw) and Hunter Park. $6. Snug Harbor.
