My SO and I drove down to Indy last night to listen to the Wood Brothers. (I did not take these videos.)
I would describe their music as southern rock with folk/blues/gospel influences. Besides Oliver on guitar and Chris on bass fiddle, they had a percussion guy (Jano Rix) who for some songs thumped a guitar modified to be played percussively. It looked like he had a mini-tambourine on one drum stick, too.
We would have stayed for the whole show, but 1) there was a warmup act (Seth Walker), so by the time the Wood Brothers hit the stage, it was already past our bedtime, and 2) there was no place to sit. The few chairs set up were reserved for people we presume won tickets from the sponsoring radio station. The crowd varied in age, with a preponderance of twenty-somethings who drank beer, danced perilously close to our feet, frequently thumbed their phones and took photos of themselves and each other (I photo bombed at least one picture), and talked, talked, talked. While we greatly enjoyed the music, we might be getting too old for the other shit.
