Ann Arbor, Mich.-based combo the Ragbirds is the type of band you expect to hear at a place like western North Carolina’s LEAF festival. Tunes like “Adoration” from their 2005 debut, Yes Nearby, play more like a Hare Krishna praise circle than a typical beer-in-hand club show. It’s not all “focus on your breathing” music, though. Bandleader Erin Zindle leads the group with her fiddle, mandolin, accordion, and sweetly infectious vocals. With congas and a full drum set tucked into the five-piece configuration, the percussion-driven tunes roll through creative arrangements and grooving hooks. Fans of Celtic, Middle-Eastern, and Latin music will appreciate the melding of influences. Plenty of electronic acts incorporate them these days, but few live bands manage to make it all work well. The Ragbirds arrive in Charleston in support of their new disc, Travelin’ Machine. Fans of that group, the Duhks, or Rusted Root will dig the fiddle-driven, multi-harmony, tabla-tapping songs.
