Just stumbled across Wolfgangs Vault – hundreds of free live concerts to stream across to your computer. Really like the fact they are full-length, including all the banter inbetween the songs too.
Impressive list of artists, though it's American classic rock orientated and most of the concerts are quite a few years old…. but heck, that was when music was music yeah!

Currently enjoying 1978 Springsteen concert…the Boss gives good banter.
