This particular track used SuperCollider to perform the drum track through various resonators, reverb, and the ending cut-up on-the-fly/in-real-time.

(For example, here is the code for the resonator:

SynthDef(\resonator, {| id, val, noff, first, panic = 1 |

var tdel = TDelay.kr(\trigr.tr, 0.001);

var freqs = Array.fill(10, { TRand.kr(100, 5000, tdel) });

var amps = Array.fill(10, { TRand.kr(0.05, 0.08, tdel) });

var rings = Array.fill(10, { TRand.kr(0.05, 0.8, tdel) });

var duckenv = Env.new([1, 0, 0, 1], [0.001, 0.002, 0.001], 'sine');

var duck = EnvGen.ar(duckenv, T2A.ar(\trigr.tr));

var clocktime = ~tmpclck.tempo;

var receive = In.ar(~fx[2].index, 2);

var input = DynKlank.ar(`[freqs, amps, rings], receive)

* duck * Lag.kr(noff, 0.01);

var send = (receive * dryvol) + (input*0.12);

send = send * panic;

SendTrig.kr(\trygr.tr, id, val);

Out.ar(~fx[3].index, send);

}).load(s);
