If you haven't seen it already, the new Bang on a Can All-Stars album is up on their website, and you can download it for free for a few more days!
I like it - there are some really great moments (which I'll let you find on your own).
There's also an interesting Nancarrow arrangement, too. If you're into Bang on a Can (which I am), you'll like this double album. All of the usual suspects are represented: David Lang, Julia Wolfe, Michael Gordon, Louis Andriessen, Evan Ziporyn...
If you're not, it's at least worth checking out the Nancarrow.
