Recently anointed as Boston’s Americana Artist of the Year, David Wax Museum has been on a steady ascent. From acclaimed performances at the Newport Folk Festival, sharing bills with Carolina Chocolate Drops and Ben Kweller, the Museum fuses traditional Mexican folk with country, folk and rock and in the process have created an utterly unique Mexo-Americana aesthetic. Combining Latin rhythms, call-and-response hollering, accordion and donkey jawbone rattling, they’ve electrified audiences across the country.
