Enzyme X is Sublabel of
Enzyme Records which features as an outlet for the harder and more experimental productions of the producers on Enzyme. All releases are 7"es and list no producer credits on the artwork or record, except for X13, which was a special celebration release for the 13th Enzyme X record. This one is called The Fucked-up Edition, 12" and has names listed on the cover.
Because of the popularity of the label they also decided to create a 'DJ Enzyme X'. When this name is booked for a party, nobody know who will perform; it could be anyone who ever created a track on Enzyme X.
