I would quibble with the genres you listed in the title, but it's whatever.

Isbell, Adams and Earle are actually all good friends too. Isbell and Adams toured together extensively last year, and Isbell regularly sits in with JTE live. Here's a couple of videos of them together:
And finally, you should definitely check out Night Beds. Debut album came out Tuesday, and they're on Fallon tonight:
Changed the thread title to more accurately reflect the music that's been posted in here so far. Hope you don't mind OP. Let's make this thread a thing guys, I'm on a mission to expose more people on this site to this style of music haha.
