Animusic

Wayne Lytle:
[at the end of the Drum Machine commentary] As with all of our environments, there's an extent to which this approximates some reality and another extent to which it violates physics in our universe. In this case, even though the structure may look somewhat physically plausible, I suspect that if you build this thing, it just might collapse under its own weight. And even if it didn't, it certainly would be difficult to move the large gears as fast and as suddenly as is being done here. But, in the Animusic universe, it's all okay.

Wayne Lytle:
[during Harmonic Voltage commentary] These bass emitters are plasma-filled. Or maybe they're filled with some kind of radioactive grape juice or something - I'm not sure. But anyway, they visualize the taurus bass pedals part.
