Avett Brothers preview for a Nashville show

Ever since seeing the Avett Brothers I have been trying to put my finger on their uniqueness: here's another little review of an upcoming show in Nashville where someone more eloquent than I tries to describe the phenomena:

For all their Appalachian traditionalism and no-fuss debt to old-guard country, the Avett Brothers have been expanding the boundaries of contemporary folk for the better part of the decade now, mostly under the radar. With a catalog of hit-and-miss attempts at dipping hillbilly rock, street-busker pickings and even a slight ranchera flavoring into their countrypolitan bluegrass, the trio's flops outweigh their wins. That balance saw a dramatic shift for the better following the release of last year's creative peak Emotionalism, which caught the ear of producer Rick Rubin. Now signed to his American Recordings label, it's likely the Avett Brothers are prepped for an exponentially greater share of the national spotlight. Rumor has it the band is currently at work on a batch of fresh songs, so this show should catch them at their backwoods best and with a wealth of new material.
