McGill University construction - subterranean remix

Loops, reverb and EQ take you into the subterranean world of this expansive university campus. Submitted by Eric Powell, who says: "The original source is a pair of construction vehicles reversing - moving way from each other, creating an interesting doppler shift. In the remixed version I play with this acoustic phenomenon - pitch-shifting and looping these two vehicles to create melodic permutations and dense textural sections."
