This sample is taken from Grey suit 7 a brief solo performance recorded in a Cardiff pedestrian underpass.
As Kenneth Goldsmith put it:
Minton's range on this disc [A Doughnut in One Hand, FMP] runs from the sounds of a man choking on his own vomit to the sounds that grandpa makes when you finally decide to pull the plug on his respirator. Minton's like a little kid who's contact-miked himself playing yo-yo with his saliva; he's a baby drooling through his cries; he's mastered the art of the multiple burp; he's perfected the craft of goobering all over his finger and then running it over his lips while moaning. I'd hate to see what his mic looked like after he was done with it. ... Minton ... forces us to ponder the musical qualities of noises that we'd rather not deal with and for that fact alone, makes this an important recording.
