Sample envy

So I'm starting to think about rythmns and sounds and riffs for BMS. Track 1 is all about the physical world, section 1.1 is about matter and the three major states: solid, liquid and gas, and so for sub-section 1.1.3 I've been thinking about what sort of sounds you might use for solidity, frozenness, ice, that sort of thing. I've heard of a lithophone, which is a sort of xylophone made with stones. I had a quick look on the internet for lithophone samples and I found somebody who has professionally sampled the skiddaw stones. One problem: it's £50 for the samples. Now I can't go buying exotic instrument samples every time I have a whim like this, they have maybe 3 minutes use tops. Sigh.
