I posted about this last Tuesday, and now it's here. The Guitar Virtuoso Pack is now available on the Xbox 360 and probably PSN (I haven't checked) for 500 MS points and 6.25 PSN bucks. What songs you may ask?
Joe Satriani - Surfing With The Alien
Buckethead - Soothsayer
Steve Vai - For the Love of God
These songs are amazing and look HARD. It's not overcharted, though. These songs are hard because they are by some of the most amazing guitar player on earth. Here's vids of the charts.
For the Love of God
Surfing With The Alien
Jesus Christ. Anybody else interested?
