The Higher Intelligence Agency at The Zap Club, 08/12/93.
The Zap was always good for gigs and of course club nights. One of those places that was a little bit grimy and scuffed up, but full of soul. Even on the coldest of Brighton nights down there on the seafront, the place was always rockin.
My only memory of this is the HIA playing behind parachute drapes and the live vocal on the fantastic ‘Ketamine Entity’ .

Did you know that the live vocal you mention was by the man who became Chandrasonic in Asian Dub Foundation?
