But Zappa was never, like, serious, he always was ironic, sarcastic, or downright clownish, and always, it seems, looked down at the audience. This makes his music sound great at a Saturday night show, and less so elsewhere.

There are many more snarky comments which Zappa directed at his audience, and any audience in general, and likely the humankind as a whole. I think this is the reason he created technically brilliant and invariably ironic pieces: he did not think that a worthy audience exists, maybe except his orchestra and a few other musicians.
(If you think he liked orchestras, you should read about his LSO recordings and how he had to rescue them by editing tapes with razor blades. He wasn't actually happy until he recorded with the Ensemble Modern at the end of his life.)
