The Ultimate Bootleg Experience is an ecclectic mp3 blog dedicated to live boots with a good number of posts up, and the links in the archives seem to stay live for quite a while.

The "Bootlegs" section over at The Rawking Refuses To Stop has a ton of great stuff, from a stripped down live acoustic Jeff Tweedy & Jay Bennet set (right before YHF was released) to a mock-up version of the unreleased new Radiohead album using the best available live tracks from the most recent tour to a rare Paul McCartney, John Lennon & Stevie Wonder jam session to all sorts of smaller gems.

Podbop. Completely stupid name. Not a bad idea. Enter your city, and it will come back with MP3 links and podcasts from bands soon to play in your town, in a "try before you buy tickets" kind of way. Works quite well for the US, other countries look like they need updating.

Live releases a free downloadable MP3 in what is sure to be a long line of overwrought and sappy tribute songs inspired by the tragic events of yesterday.
