Jake Schepps and Expedition

Progressive-bluegrass mandolin monster Chris Thile made waves last year with his all-Bach recording, but crossing over works both ways—a point proved tonight by banjoist Jake Schepps and his quintet, Expedition, who’ve been commissioning new pieces from bright young composers. This gig marks the NYC debut of a composition by Matthew McBane, a fiddler known for his own edge-blurring work in Build.
