Bipolar promo cutz are back with more deep obsessive disco gems. "Rock Groove Machine" is looped up to have tense dance floor flow with emphasized guitar riffs. On the flip, you have another hidden disco track from 1975. Kay Sputnik increases the track length to 8:50, carefully looping the most uplifting parts in the song to justify its disco groove with natural flow. Played by Theo Parrish.
