Album: Punch Brothers, Who's Feeling Young Now? (Warner Bros)

A follow-up to the oddly compelling Antifogmatic, in which a string quintet (mandolin, banjo, fiddle, bass, guitar) attempt to plot another course betwixt the markers defining classical, folk, pop, bluegrass and jazz: a sort of virtuosic spindrift of ideas which defines itself by the things it entangles in its jetstream of time signatures and dynamic adjustments.

Chris Thile is the most remarkable mandolinist in the world; fluent, articulate and sometimes just a little too clever to be truly engaging.
