I recall my first encounter with it. One morning, coming down off of some various chemicals, I went over to a friend's house. He sat me down on the couch, saying "You MUST hear this! Right now!"...and slapped on "USSA". Loud.
I remember my reaction to it was something like you might've gotten if someone had aimed an industrial sandblasting gun point-blank at my brain.
I went out and got a copy later that day, of course.
