This shidd is great bro. Good work. Did you craft every guitar segment beforehand or is there some improv involved as well? I'm guessing the former, since everything fits neatly.
Yoooo found this while trying to find some transcriptions of Isamu Ohira's Slipstream from GT3, but I agree; GT4 also had some great stuff too! I'd pay you to do transcribe all the keyboard/organ solos in Slipstream... seriously.
