Here's one gig where I was asked to play last minute, didn't have time to go home and get any gear so I played using random objects found at the venue and borrowed from a friend's car (he'd just picked up a free vintage echo unit etc), a borrowed multi-fx with loose connection, the DJ booth headphones as mic, unamplified triangle and haribo wrapper. Hey, i never specified an especially
GOOD gig! :D

Kicking a fire extinguisher around an underpass counts as a gig too
Recording-wise I guess I mean found-noise eg one of my tracks is just raw audio from a video camera attached to the front of a taxi for completely un-noise-related reasons (can't remember which track right no so no link), and have done some with borrowed gear after a quick go on it.
Maybe overstated it ha. But I don't feel like I have one totally essential piece of gear. Some kind of mixer and some things which make/feedback sound will do if all else fails
