i liked the first one, it had a 99 dnb feel to it, and is quite a neatly made track! tech itch make nasty beats but that got a bit repetitive after a while.. ^^
and pretty much every single release from yellow stripe recordings. bought every single tune they released to support the dj's because they're my friends etc,
this one is probs my fav (and almost everything else with mathizm in it)
At work so all the youtube links are blocked so im not sure what your after really. But first thing that comes to mind whenever someones says "Dark" is Rene Lavice - Dungeon. Raw tune.
