"AIR RAID" (beatbox; needs earphones)

Although I'm a doctor and professor, I've always had a secret drive to beatbox. So, I finally bought a proper loop station. I was playing around and created an air raid siren. The rest just followed. Here's my 1st loop song (requires earphones to hear full bass spectrum and drop at 2'02"). Sound and video sync slightly off because I'm using Zoom to record and it doesn't seem to work well for this (I'm sure there are much better ways!)
