I recorded a track earlier this year by duct-taping a cheap tape recorder onto the intercom speaker of an old rickety elevator inside an old school building that's been there since like 1900. I hit record, turned it on, got in the elevator, rode it up a few floors, then shouted my lyrics at the floor while I scratched at the lid of an aluminum trashcan with a carving fork. No effects or gear, no amplification except for inside the intercom system I guess, no post-process done save for me recording a sample onto the start of the tape from the news on TV. That was pretty stripped down for me.
