It’s been a Jason Isbell and Drive-By Truckers week. On the way home from Santa Fe, I listened to Isbell’s latest. On Tuesday I listened to a podcast interview with Jason’s former bandmate in the Drive-By Truckers, Patterson Hood. Today en route from Tulsa came Isbell’s “Southeastern,” and tonight I re-watched a segment from CBS Sunday Morning. About five years ago I saw the Truckers at Cain’s Ballroom in Tulsa. This was shortly after Isbell had left the band. It was a fine show, but something about it wasn’t real. The persona of rough Southern rockers seemed a bit contrived. Meanwhile, Isbell was on his own, getting sober — and simultaneously, getting a lot more interesting. His “Southeastern” has more courage and soul than anything since Sam Baker’s “Pretty World.” Vety few artists cause me to tear up with every listen. Jason Isbell is one of those artists.
