This is pretty cool. The first 6 minutes or so are a pretty straight performance of "Lateralus" with Kirk seeming to double Adam's parts, but when it hits the middle section with the repeating bass pattern where they usually insert a drum solo, instead Justin breaks into "Orion" and they jam on it for a while, interweaving bits of "Lateralus" into it.
And he only abuses the wah pedal a little bit, near the end, not during the jam Adam uses more wah (and better, and more tastefully) than Kirk
Edit: Helps if I link the correct video
