I saw The Last Bison open for GSBG last week and it would be awesome to see them play Telluride. It was actually my second time seeing them as we accidentally stumbled into one of their shows after seeing Noam Pikelny a couple years ago.
NPR called their sound “Classical influenced southern folk rock". I think of it more as Punch Bros. meets Edward Sharpe. Doesn't make sense to label it, but just trying to give you an idea of what to expect.
