Just to satisfy my curiosity can anyone kindly identify the 2nd protagonist from this question?

Peculiar question posed the other week and as per usual the person who asked it impolitely ignored my query seeking clarification as to who these two people are :

OK the first one is Hermann Nitsch but then who is this Matthew's fella ?

I found this, presumably one and the same but what the hell is with the absurdly pretentious name, I mean seriously! that can't be real.
Is it a pseudonym ?

It refers to John-Luke Mark Matthews (detect a bad joke emerging?), the pseudonym of a composer of joke pieces (many of which can be found on IMSLP). I have no idea who this person REALLY is, but he seems to be trying to be a latter-day PDQ Bach (Peter Schikele).
