Live Music Archive (free-n-legal download centric)
http://www.archive.org/browse.php?collection=etree&field=%2Fmetadata%2Fcreator
stumbled across this site which has loooads of live recordings, all free-n-legal. Admittedly, i haven't heard of most of the artists but there's a lot of DiS friendly people as well (want 77 different Mogwai concerts? You got it)
