It was a 7 minute ambient track Jeff posted on bandcamp last night. Looks like he removed it, he later tweeted something about the mix not being right.
It's sooooooo good I miss Jeff and can't wait for a new album / tour next year (hopefully) Only complaint is not doing the whole back half of Worry but most of all no Rainbow
Idk if it’s just because I’ve been listening to way too much of The Hold Steady lately but that’s definitely Craig Finn towards the end of Ambulance Blues, right?
