The World Famous Grassholes play high-energy bluegrass (yes, a little bit like that Billy Strings guy, but also like Greensky and Leftover Salmon and Mighty Poplar, etc.), a mix of original compositions, classics, and cool covers. It’s good for dancing and nodding your head and tapping your feet, and meant to be enjoyed with friends and family. Part of a long legacy of performers that goes back to 2000, the Grassholes feature Heather Kahill on fiddle, Merrill Marsh and Sam Pfeifle on guitars, Flann O’Brien on the stand-up bass, and Field Rider on Banjo and harmonica. Everybody sings a bit here and there, whether you like it or not.
