A Guitar Hero 3 demo was shipped with Tony Hawk proving grounds. For those of us not interested in the new Tony Hawk (anyone whos played skate), you can head over here to download the demo. Some people have figured out how to extract the demo to a playable ISO. Just burn the ISO to a CD or DVD, stick it in your 360, go to demos and rock out. There is a chance your console wont be able to play the burned demo, but such is haxory.

Included songs:
– “Lay Down,” Priestess
– “Even Flow,” Pearl Jam
– “The Metal,” Tenacious D
– “Hit Me With Your Best Shot,” as made famous by Pat Benatar
– “Rock You Like A Hurricane,” as made famous by the Scorpions
