Hold it there Satriani, you still got a couple more things to learn before you can singlehandedly drag your no-talent buddies along to that coveted Battle of the Bands Trophy. What about learning the actual guitar PART (after the riff) in "Crazy Train," or get some soul into your fingers by learning the bridge to "Sir Duke." Also, learn your modes already. If you know your Greek Columns, you're partway there, except there is no "Corinthian Scale."
