This production name was an alternate alias that a few of the Almighty Associates members used for their more club oriented Hard Dance side label Euphoric Records. It was named after the original location that the Almighty Records studio was located at Cromwell Place, Highgate, London, Unit 4. The actual name, Unit 4, was the number of the flat that Almighty was located until the later 2000s. As of now, the production name Unit 4 is no longer in use.
