they only did *releases* on 59 records.
they have done *remixes* on other labels.

by the way I also believe the Hatshepshut projects are theirs.

that's it.

Zatox is a very nice Italian guy called Gerardo Roschini, I've got close contact with him and he makes wonderful releases but he certainly has nothing to do with Brain Ovulation.
