Sonic Groove Old Gold, the new sub-label of Sonic Groove releasing rare techno obscurities from decades past, debuts with two rare 1996/97 deep acid gems by CAT 1, originally released on Germany's Overdrive. With scarce original copies fetching very high prices online at over €100, "Revolution" and "Axion" have been updated for modern sound systems. Adam X has layered new, prominent kicks onto both tracks, bolstering the drive for today's dancefloors while keeping the original arrangements 100% intact.
