Last night, Jason Isbell closed out his four-night run at the Ryman Auditorium in Nashville, TN with a visit from country legend John Prine and photographer/harmonica player Danny Clinch.

After playing his new album in full the night before, Isbell came back with another slew of Something More Than Free tracks last night, including a run of “Palmetto Rose” with Clinch on harmonica. The song before, Clinch sat in on a cover of Little Walter’s “My Babe.”

For the encore, Isbell brought out Prine to help him with a cover of the elder songwriter’s “Storm Windows” before closing out with “Super 8” and “Codeine.”

Isbell is back on the road continuing his current extensive tour on October 29 at Potter County Memorial Stadium in Amarillo, TX.
