Day Three Hundred and Eighteen

In the ongoing comedy of me playing/recording inanimate objects and getting strange looks from passers by, I heard this great low tone today in a hospital corridor and went to check it out. It turned out to be an air conditioning unit, and it sounded great! I made three tracks out of the recording, each at a different pitch, and added them to the fire hydrant loops from yesterday - one pitched down and one slowed down.
