These sounds are from directories found through Google searches... mostly musicians trying out gear, practicing, jamming, etc. (like walking around a Guitar Center store) My software randomly pulls from this set and then loops/collages it together, all in realtime here in the browser. Different sounds will come and go every few minutes, the frequency of this depending somewhat on the load-times (related to your connection speed). It perhaps takes 1-2 hours of listening to fully hear the piece. Based on what sounds come up together, the feel of the music can quickly morph.
