Believed to be second pressing of Unit 1 - Modular Expansion. This record was repressed with the track "Tension Dream" instead of "Hip In The House". This was probably due to author rights problems because of the use of vocal samples from Ya Kid K in Hi Tek 3 - Spin That Wheel in the "Hip In The House" track.
