What happened?
The new millennium brought about a drastic change in Autechre's style, demonstrated by Confield (2001) and Draft 7.30 (2003).
When you say drastic change, was it a positive or negative change?
CANNOTANSWER.
What lead to the drastic change?
The title track from Gantz Graf inspired an iconic video by British designer Alex Rutterford, featuring an object (or an agglomeration of objects) synchronized to the music.
Can you tell me a little about the video?
featuring an object (or an agglomeration of objects) synchronized to the music as it morphs, pulsates, shakes, and finally dissolves.

Question: What happened afterwards?
Self-contained rewrite: What happened after Alex Rutterford made the iconic video?
