Phat Grass will perform Friday, Aug. 31, at She Doesn’t Like Guthries. While a new band in the New England bluegrass community, Phat Grass is made up of musicians with many years experience who have performed individually and with Maine-based bands throughout New England and beyond. Phat Grass is a band rich in traditionally rooted bluegrass but also leans toward the progressive side of the bluegrass genre. The show starts at 8 p.m. No cover charge. Guthries is at 115 Middle St., Lewiston.
