Rahsaan Roland Jerk
An act of masturbation while playing a saxophone. Rahsaan Roland Kirk, famous for playing two and three saxophones simultaneously, had the keys modified on one of them so that he could play all the notes on one while also fingering the other.
On Raphael Pannier's new record, Chad Lefkowitz-Brown plays like he's having a Rahsaan Roland Jerk. I bet he got his keys modded so that he could finger two horns at once!
