A younger gentleman sat down on stage, plugged in a bass guitar and sat with it. He strummed it a couple times and then put it on his lap. He then jammed a butter knife into it. I thought it was a weird weird tool to use to tune a guitar, but whatever.
Then he pulled out a bow and began fiddling that butter knife. It was the most wretched sound I've ever heard intentionally amplified.
It was horrible, and he wouldn't stop. I finished my drink and looked around the room. Everyone was locked in, some even nodding their heads as though there were some rhythm to nod to. There was not. There was no discernable difference in pitch or tone no matter where on the knife he played. If he could predict the sound being made before he made it, it wasn't obvious.
I had a great seat in the middle of the bar and didn't want to lose it for my friend's show, so ordered another drink. But the guy was relentless, and the crowd was relentless in their appreciation. I slammed the drink and gave up the best seat in the house to smoke outside until it was over.
My friend's performance was excellent (which I watched later from the back of the room). Later I was with him and a couple other patrons and tried to describe how awful the knife guy was. The others who saw it said I was being closed-minded. I worry they cannot hear well.
The only art in that room was watching that crowd accept that wretched noise as performance, simply because the person making it happened to be on stage.
