The first part consists of a Chapman Stick through a MIDI converter to a pc for the initial drum sequences, then a kalimba, then some toms and cymbals, all looped with a Boss RC 300.
The second, the core, is just the stick through an EHX Bass Microsynth and Cathedral reverb. Again to the Boss RC 300, using the pitch bend and the fade out function of itself at the end, so only one track of 3 still remains when returning to the original pitch.
The two parts were recorded live but separately and then mixed together. It takes "only" 11:59 minutes. At 12:00 we espect the end to come.
