Bluegrass. Swing. Hot jazz. Prewar blues. Southern soul. New Orleans funk. The Dustbowl Revival is what you could call an American roots orchestra with eight full-time members — and they play it all, mashing the sounds of traditional American music into a genre-hopping, time-bending dance party that coaxes new fire out of familiar coal. This isn’t a throwback band. It’s a celebration of the sounds that have kept America moving for more than a century, performed with all the flair of a medicine show and rooted in the sweat and swagger of a juke joint song swap.
