Have you had enough of the kitsch
Coming to us from Washington?
Are you tired of the unending effort to entertain?

You will not find any of it
At SEM concerts

Our music
May confuse or contradict itself

But
Not a single moment throughout history
Was it otherwise in the case of music
That prevailed (eventually)

-Petr Kotik, April 2026
