Anthony talks about this setup here:
He was really interesting to listen to on the Mylar.Melodies Podcast too
Though back in the day Surgeon wasn't my listening of choice, thats got nothing to do with Talent or Creativity of course.
And I'd like to point out that Surgeon is an especially cool dude after being awake for 30+ hours and having Denny's for breakfast afterward.
Yes, really. He seems very humble, very friendly. Very patient too. A whole attitude and philosophy which you can find embodied in his works. Respect.
