Rubric (1983). Philip Glass /no, not sin tax/

the syntax of things mentions an upcoming trip to Nashville to see Philip Glass, and promises proper concert etiquette:

(if anyone out there is going to this show, i promise that i’ll try not to be the idiot with the lighter yelling “RUBRIC!” or “KNEE 1!”)

As one who always liked the study of syntax, in the computer science sense anyway, I might be disappointed with the syntax' interpretation of the original e.e. cummings. But there's also a Saturday Night Live YouTube of Philip Glass playing Rubric, so I'm ok...
