Here's an interesting tape of varying sounds. The first two songs, "Reflect", and "Settle It", take you from contemplative instrumental to frantic post-punk Euro-pop. This is bizarre, alternative, different, wacko, uh, er...very entertaining; with lots of effects, sound effects, and spoken voices thrown in. Definitely not metal, but I'd recommend it as a novelty alone. If ya want to hear something genuinely strange, get "Soul Windows".
