Set fire to a pop diva.

(Kidding. Don't do that)

I've done a lot of hydrophone stuff - often times something that sounds good above can sound not so good below - the speed of sound is increased underwater and that can lead to a "tinnier" sound. The trick is to sample at 96kHZ (or as high as possible) and then play back at 48kHz so that you bring the out of hearing range harmonics into the audible range and generally add low freq content.

I did a piece for lots of bowls floating on the surface of a pool, where you toss ice into the pool - sometimes it hits the bowls, sometimes it just splashes etc and recorded that with hydrophones at either end of the pool (you need greater physical separation than normal for stereo because of the speed of sound increase)
Anyhow, the underwater sound was disappointing at the usual samplerate, nice slowed down though. And a nice piece to perform at a party if you have a swimming pool. Take drink from icechest, take a piece of ice too, toss ice in pool. Repeat

I just found -this- by accident

Cut the strings with scissors (different instrument sound)

I like the idea, personally I'd like a piano break, play a key, hold and then smash the whole instrument with a big concrete block. Some round robin and velocity layers would be cool too.

I hear a hangdrum here that sounds like it comes from (Storm Drum 2).
