It's easy to assume what a band named Boulder Acoustic Society might sound like.
They come from Boulder so they're obviously hippies, maybe even communists. And they probably do some jamming, possibly exploration of older sounds, maybe some roots and bluegrass music involving dancing, hula-hoops and twirling in place. Then, they have "acoustic" in their name, so they prefer hollow wooden instruments and plugging in is optional. So are shoes. "Society" probably just has something to do with them being commies.
Now, as easy as it might be to geographically profile such a band, you'd be surprised how the cards actually fall. Sure, they have some older sounds: Appalachian folk, Gypsy, traditional bluegrass; there's also a bit of jamming. And they are acoustic purveyors: accordion, fiddle, guitar, ukulele and upright bass. However, there are enough hooks, indie-folk sensibilities, vocal harmonies and jangly choruses to get even the biggest squares on the Grove steadily shaking their groove things.
The Boulder Weekly summed them up as, "Experimental, but not pretentious. Fun and serious in all the right places. Weird, but not in a ‘look at how weird I am’ way."
Opening for BAS will be local act Andy Byron and the Lost River Band, a country-rock group who have opened for Travis Tritt, Johnny Lang, The Charlie Daniels Band and Michael Martin Murphy. Andy and his talented six-piece band know how to rock a crowd, so make sure to pound your happy-hour drinks and scuttle hurriedly to the Grove.
