Punch Brothers—whose name is taken from the Mark Twain short story, Punch, Brothers, Punch!—features a formidable lineup of musicians from the worlds of bluegrass, folk, and traditional music: composer-singer-mandolin player Chris Thile, guitarist Chris Eldridge, banjo player Noam Pikelny, violinist Gabe Witcher, and bassist Paul Kowert. The band followed its 2008 Nonesuch debut album, Punch, with the Grammy-winning Antifogmatic in 2010 and Who's Feeling Young Now? in 2012.
