Have a scoot over to thefreesoundproject where you’ll find… lots of free sounds!

I particularly like the waterphone samples but there’s plenty there for you to rifle through and assemble into some grand aural masterpiece.

I’ve just wasted too much time listening to random samples… I warn you, it’s addictive!

And if you’re a bit of a samplist / archivist yourself, why not join up and contribute? I think I shall send some widdly prog solos their way. 😀
