Steve Schwartz takes on Jan Jarvlepp's opinions of 20th century music,
several times implying that Jarvlepp is rather uninformed.  He also says

In fact Jarvlepp is a composer and a respected one among those who know
his work.  He has as thorough a knowledge of 20th century music as anyone
I've met, including knowledge of Schoenberg and Webern.  He has a PhD in
composition.  He's told me that his education was geared to producing an
avant- garde composer.  I've often wondered whether his teachers wring
their hands wondering where they've gone wrong, since he has chosen to
develop a style that people actually want to hear.  For a while he bore the
nickname "Mr. Postmodern" in Ottawa, where he lives and works.  However,
in the years that he was director of a local new music society, he provided
for 20th century music of every stripe, including some pretty fierce
avant-garde stuff.
