I did a lot of electronic/experimental music as an undergrad, so I can pick up on sound processing pretty well. And I'm a bit of a geek about sound and timbre in general.
Oh, yeah, I knew that the pacing was due to PC actions, not the GMs and NPCs. On the one hand, it was a perfectly reasonable approach on the part of the PCs. On the other hand, boy was I ready for it when we finally got out and took action.
