I'll have a root around my records later, but I know for sure there are more alias' than just hatshepshut and B.O. I'm near 100% certain that they are also Acid Step who have had at least one release, and it is the name that the remix of Kicks & Bass is under.

On some of my Zatox EPs it lists Stephano Pignat as producer, and i'm certain that is one of Brain Ovulation. I'll take a look later...
