That reminds me: Pan American was also a great live act. He played all sorts of instruments and futuristic noise-making gadgets, including stuff he clearly made himself.
Well Kevin Drumm actually opened for them, and it was the nastiest, noisiest crap I've ever heard. I've never witnessed so many people wishing the performer would just leave, or die. So it didn't set a good mood for Autechre and their own brand of what, for me, has become noise.
