Bluegrass music traces its roots to Appalachia. Its melodic sounds, simple chords and delicate acoustic string instruments make the genre an old-timey favorite. East Coast fans of the nostalgic music can rejoice this month: FreshGrass returns to MASS MoCA for its sixth year. "It's three days of bluegrass across a 16-acre, 19th-century factory campus. Lots of places for people to bring instruments and sit and pick and play, in addition to three main stages, in addition to pop-up concerts in the MASS MoCA galleries which festival goers have access to all weekend long," says MASS MoCA Director of Communications Jodi Joseph. "It's a really great party." This year's lineup features well-known bands like Old Crow Medicine Show, Glen Hansard, Lau, and The Devil Makes Three. Emerging duos, bands, banjo, and fiddle players will compete for the chance to win $30,000 in head-to-head performances. FreshGrass takes place from September 16 to 18 at MASS MoCA. Festival passes, single day, and VIP tickets are available for purchase.
