Duo Glide has a metronomic spine. It started as a beat box rhythm that I played drum on top of. I'm not the best drummer but I have a nice feel. The beat box and my drums were slowed down approx 4 semi-tones. The song was the built on top of the slowed down groove. If you watch the Duo Glide scene from the film Here Is What Is you will see the actual overdub take. Moral of the story, curious laboratory preperation with performance overdubbed on top. The recording was done by Adam. No reverbs were used, only slap echos.
