I made a track without ever listening to the output of my soundcard. Only by looking at different kinds of visualizers and analyzers I was able to determine what I was doing. That track was then called "No Ears". The No Ears-EP also contains the track "Yes Ears", in which I took said track and reworked it while being able to listen to it.
This video shows how I made the No Ears-Track: https://youtu.be/gu6wuIcDH_Q
