i love going through old backup dvd of projects from years past - mining for samples, as i call it. i'm always amazed at what little gems can hide out in the dust of time.
i found an old piano field sketch and have run it through various stages of animated effects - a slowly evolving composition of morphing and temporally layering distortions, reverbs, and reverse effects... the three classic effects that (hopefully) won't go out of style any time soon...
