This is an apparently undercover effort from special K who's gone to HUUUUGE lengths to keep his identity secret now hasn't he? Bascially it shows his inconsistency quite well. One side is real good and one is utter cack. "Back up" is the badboy on this slab and is pretty much a combination of all the things i've liked about special K. It's a very rhythm based tune with a real simple square wave type bassline with a chunky as fuck beat and bangin bongos clattering away over the top. Pretty much the pick of the huge wave of special K/D'cruze tunes out there right now. "Rubb" was just really boring. Really tame sounds all round, and I can't even remember what the tune goes like at all. If you're gonna chill it you at least need a strong melody of some really interesting sounds to keep it going.
