This is a direct snippet, word for word, from a Guitar Word interview with Joe Satriani…
Guitar World: Since we last spoke for an extended interview, two of the biggest pop-culture phenomena have been Guitar Hero and Rock Band. What’s you’re take on them?
Joe Satriani: It’s funny you ask: Both game systems have just licensed “Satch Boogie” and “Surfing With the Alien” for upcoming versions.
Hmmm…well, he definitely has two songs in a game. I am guessing it will be Guitar Hero IV rather than Rock Band 2. Huge thanks to Ryan for the transcription!
