Learning about Brett Dennen has definitely been one of the more fun hunts I've done in quite a while.  His lyrics sometimes border on a short story set to music - imho at least.  I can be a hard sell so surprised myself by taking to his unique singing voice very quickly . . reminiscent of hearing Cat Power for the first time. 
From what I've read / seen so far,  BD seems very likable . . not a necessity but always a nice bonus. 

Found this of him doing "Make You Crazy " on CBS just after seeing his shoe store video of the song. Flipped a coin &amp; used the CBS link.

Appears I'm sold on Mr. Dennen . .  GPN musical pairing  should be interesting for the audiences.  Hate to fall back on that poor overworked word but am still wrapping my mind around it.
