Jason Isbell & the 400 Unit w/ Amy LaVere is a concert at the Ryman Auditorium in Nashville. Isbell brings his heartfelt, road-worn Americana songwriting and the 400 Unit's full-band sound to one of the most storied rooms in music. The Ryman's wooden pews and gorgeous old hall make every note feel close and personal, and the room has a warm, legendary glow that's hard to match. Amy LaVere is also on the bill, adding her own roots-rock touch to the night.
