Psychological Calisthenics

From Christgau's review in The Village Voice of the new Sonic Youth record (which, by the way, I will be acquiring as soon as possible):

All of which I find pretty exhilarating. Of course, you may not. When Murray Street came out in 2002, non-old Amy Phillips notoriously asserted in this very newspaper that since Sonic Youth hadn't made a good album since (1995's) Washing Machine, they should break up already. Who's to say her opinion isn't worth as much as mine? Me? Well, yeah. One concept the non-old have trouble getting their minds around is the difference between taste and judgment. It's fine not to like almost anything, except maybe Al Green. That's taste, yours to do with as you please, critical deployment included. By comparison, judgment requires serious psychological calisthenics. But the fact that objectivity only comes naturally in math doesn't mean it can't be approximated in art.
