No telling what'll be on the set list Friday when Jason Isbell brings his 400 Unit to the Grand Theater at Foxwoods, but here's what might happen and what it would mean. Let's say Isbell and company play the following tunes in a 12-song set — from their own albums and/or from Isbell's days in the Drive-By Truckers — in whatever order works best for the momentum and dynamics:

1) "Elephant," 2) "If We Were Vampires," 3) "White Man's World," 4) "Danko/Manuel," 5) "Something More Than Free," 6) "Decoration Day," 7) "Anxiety," 8) "Goddamned Lonely Love," 9) "Traveling Alone," 10) "Songs She Sang in the Shower," 11) "Cover Me Up," 12) "Never Gonna Change," (encore) "Super 8."   

I don't want to bite off more than I can chew, but there just aren't too many songwriters in any genre working right now that can choose a dozen tunes that can compete with that list. They're out there, obviously, but this Isbell dude is a freakin' genius. Great band, too.

Oh, here's one other thing. Isbell/400 are OPENING for Nathaniel Rateliff & the Night Sweats, so I assume the headliners must be pretty good. They'd better be.

Nathaniel Rateliff & the Night Sweats, 7:30 p.m. Friday, Grand Theater, Foxwoods; opening for Nathaniel Rateliff & the Night Sweats; $65-$90; 1-800-200-2882.
