The symphony is notable for its multilayered complexity—typically requiring two conductors in performance

I can’t imagine that this is pleasant to listen to.

At first I thought, this was the same beats, just with staggered emphasis, but no, that's 30 eighths in the timespan of 14 eighths.

So, it's like the bassoons are playing sixteenth notes, except that they're decidedly not in sync with everyone else.
At first it'll sound like they're too early. Then their offbeat sixteenth will sync up with the on-beat for everyone else. Then their offbeat will sound like it's too early compared to the on-beat, until they sync up properly again. Well, and then you do that cycle a second time, because they have to fit two extra notes in there.

Yeah, that does seem quite impossible to conduct, but even if you set up two metronomes, that'll throw even good orchestras quite easily...

it's fair play for making the drummers play polyrhythms. I'm sure you can manage it with two hands.
