I composed this track and performed it live while limiting myself to using three electronic instruments: Novation Circuit, PreenFM2, and a Moog Sub 37. Afterward I added a recording of a Tibetan tingsha bell that I captured using a matched pair of Rode NT5 condensers. The instruments were sequenced using the Squarp Pyramid, which might technically be considered a fourth instrument, but it is not a sound source.
I continually revisit dogmatic approaches to making electronic music and this approach in particular may yield some interesting results. The last collection I made like this was back in 2013 and can be found in the post Builders of the Fauxpocalypse: a Dogmatic Approach to Music Making.
