I don't know how long this will be up, but go to http://www.peavey.com/ Then click 'Launch Webcast'. Another window should pop up. Click 'Watch Concert' It requires quicktime.

This guy, Joe Satriani, is a VERY good guitarist. If this doesn't stay up, try to download him or search him. He plays really fast and really good. I recommend you listen to him if you like rock, or like guitar. Or if you're just curious. :D
