Mandolinist Chris Thile, guitarist Chris Eldridge, bassist Paul Kowert, banjo player Noam Pikelny and violinist Gabe Witcher are Punch Brothers—a virtuosic and freewheeling quintet who make their long-awaited return to the Festival after their sold-out 2009 Spoleto debut. Their new album, Who’s Feeling Young Now?, contains some of the most exhilaratingly direct, sonically daring performances the group has ever recorded. Vanity Fair has hailed it as “their most expressive work yet as an ensemble—sophisticated, pop-y, kinetic and profound, all at once.” The band has matured together on the road and in the studio, while their approach to writing and performing has, conversely, become looser, simpler, and more unaffectedly youthful.
