Here’s a 2010 feature on Squarepusher in which he talks about his live set-up and his approach to making music. I found it on a thread, so it’s a couple of hard-to-read jpgs, but it’s totally worth reading for both the technical content and the artistic philosophy. My favorite quote from the interview was:
“My advice to anyone who’s reading this would be: Don’t worry about what I’ve got. Don’t worry about what anyone else has got. Take whatever’s in your studio and make music. The most important thing is that you keep the free flow of ideas. Keep pushing your imagination. If you can only afford two bits of gear…. fine! Use them. Push them as far as they’ll go” (Squarepusher 2010)
