tune id from hs human traffic

if anyone has a copy of the mark eg tape from the first human traffic tape pack from code in birmingham you may have an idea of the tune im on about. It has no vocals sadly which may have mad it easier to identify. mark mixes it in after megaphone "do you have a blow" on subway and before alien pulse "psycho confusion" on zoom. It has a very intense high pitched, piercing tune and a nice driving bass. More of a hard trance bassline than a hardstyle. not heard it being played very much but did get to hear it once more by mark at slammin vinyl around the same sort of time. :?: :?: :?:
