There are bootleg sites out there with performances from the current tour of most of those new songs--I posted a link above to one I think is absolutely great, but I don't wanna listen to the others because I don't like previewing albums when I know I'm going to buy them anyway. Based on "Walk Like a Giant," though, I have a feeling this is going to be a good'un. I like Americana, by the way, give or take a song or two. (Don't have much use for "Gotta Travel On"--I'm not sure Pegi and Crazy Horse are two great tastes that go great together.)
I'm bummed that I won't see them on this tour--I'll be out of town for the MSG show and I absolutely refuse on principle to go see anything at that loathsome Barclays Center.
