You can stream three new Decembeists songs (performed live) on the Decemberists’ fake Pure Volume page. (thx Brooke)
And if you didn’t know already, the Decemberists are on the Internet Archive. Right now there are 10 live shows up there for download. You’ll need lossless FLAC software to listen to them though.
