Trip has heard the whole album and loves it. I've heard a couple of tracks and concur. Middle Brother is a summit meeting between members of Dawes, Deer Tick and Delta Spirt (members of Devo, Decemberists and Dire Straits: unavailable), and they play a loose-limbed Cosmic American Music that would make Gram Parsons proud.

Here's the song that gave the band its name (or vice versa):
Middle Brother, "Middle Brother"
