Right. So.
A cunning plan.
Basically, the whole thing with having a soundscape in the background and music on top got me thinking.
Or, at least that as well as you saying something about creating an atmosphere before the piece starts.
I really like (or at least, I feel that) that pieces don't exist in isolation from the rest of the world, but are part of it. So creating a less jarring transition from being 'outside' of an event space to being a viewer of the piece seems like an interesting thing to do.
I thought that maybe I could get a bunch of reed organs (these things) and either hang them up or stand them up around the space, with notes taped down, so they make a sort of 3D background hum. Probably 4- one on each wall, and with each of them with different notes taped down.
Also, going along with the atmosphere before the show idea, if there were enough, maybe have more of them hung outside the venue and in the foyer bit, with signage stuck on them pointing to the hall.
Something along those lines. They are pretty cool instruments, or rather... they are badly made rubbish things, which I like.
I'm afraid that that's pretty much it- nothing too amazingly exciting, but enough to get me all a-flutter about things.
