With the April 23 release of her debut full-length, His & Hers, Boston singer-songwriter Xenia Dunford showed her evolution as a musician and her thoughtfulness as a person. Featuring a combination of jazz piano and folk rock wrapped up in a nice package of pop sensibility, it is as much a culmination of her EPs, Lonely Streets and Xenia Dunford, as a new peak in her young career. Catch her on the River Stage of the Black Potatoe Festival in Clinton on July 12 at 7:30 p.m. A pass for the day costs $25 and a pass from for the entire five-day festival costs $80.
