Inspired, versatile and entirely unique: These are among the words that have been used to describe the Boston-based act Della Mae. Steeped with timeless lyrics and rootsy influences, the multi-instrumental group creates original music that draws on both traditional and avant-garde styles. With a desire to focus on their personal lives and solo work, the foursome took a hiatus last year with a promise to make a few special appearances in 2017—and it seems that the equality-minded Festy Experience was a compelling date to ink in their calendars.
