Folk music certainly seems to be on the upswing again with folks like Bon Iver and the Fleet Foxes enjoying tons of press and popularity (at least as much as an indie act can get). Proof positive is The Avett Brothers' rapid rise during the last couple years. Seth and Scott Avett have been playing together in their current band for about nine years, releasing CDs and touring modestly until their first appearance on the Conan O'Brien Show in 2007. After that appearance, they've been asked to open for Dave Matthews Band, Widespread Panic, and are regularly selling out their own headlining shows. To see these folk-punk-bluegrass-ragtime act in all its high energy glory, check out the web site and ready about $26 for a ticket.
