A frat boy would never frost his hair.
I also think that most of the uses of 'overproduced' in this thread end up meaning something different than they should, in order to really get at what makes BT's music less than compelling. The problem is not that he uses lots of effects and cuts and processing and such. That cuts across good and bad electronic music. Arguably, autechre's music is even more 'overproduced' than BT's in this sense.
But autechre's music is better because it's better composed, or sequenced, or arranged or whatever. In particular, I think they have a much more interesting and funky sense of rhythm than BT (or Richard Devine or Otto Von Schirach or Telefon Tel Aviv, for that matter -- all equally 'overproduced' artists in both senses of the word I am drawing out here). Autechre know how to rush and pull back on the beat, when to drop a snare, how to do more surprising fills than triplets and sixty fourth-note snare rushes. They must just be better at 'humanizing' their beats, whatever that involves. Because you feel the beat of their tracks in a much more visceral way than you do with those other guys.
So I thnk it has little to do with plugins and everything to do with 'feel,' for lack of a better word.
