etree.org --- live music free and legal

etree.org is a music trading site which specialises in making available live recordings ('bootlegs') from trading friendly musicians. Originally a relatively exclusive club, the advent of bittorrent has the music much more accessible to the non-fanatic. Bands such as The Grateful Dead are of course mainstays, but there are also many current bands such as Black Crowes and Phish.

With about a dozen new listings every day, there is lots of music to listen to, even if the breadth of the collection may leave something to be desired.
