Martin Earley (guitar and vocals), Devin Mauch (percussion and vocals) and Calin Peters (cello and vocals) formed the rootsy folk trio the Ballroom Thieves three years ago in Boston. But they burst onto the scene—first in their hometown and then throughout the region—when their five-song debut EP, The Devil & the Deep (stream it below), filled with foot-stomping energy and three-part harmonies, came out in 2012. A four-track self-titled EP (stream it below) followed in 2013, and thanks to their rousing performances, unique instrumentation and topnotch songwriting, the Ballroom Thieves (above, doing “Coward’s Son” for Audiotree Live) are now making a name for themselves beyond New England. Find out for yourself why tonight at Mercury Lounge. Soulful psychedelic-blues four-piece the Tontons, out of Houston, open the show.
