hmmm now i'd definitely disagree with you there - the Selector video works so tightly with the music, something that mr C himself has admitted he has been striving for throughout his career. I think it was in a Creative Review piece on it they asked - what came first, the video or the track?_Kinda sums it up i feel. The Bjork vid pales into comparison imo.
As for weakest pieces - His Jesus Jones vid has gotta be a contender.
Cant say i ever got into squarepusher tho.
