Harthouse Mannheim assembles a terse Techno sampler on CD — Various Artists collects tracks from Hardfloor, Extrawelt and Groove Rebels alongside cuts by Human Resource and Alexi Delano. Hardfloor supplies 303-driven acid thrusts while Extrawelt contributes widescreen, hypnotic Techno; Groove Rebels and Alexi Delano keep the mid‑tempo, club-focused propulsion. Useful as a snapshot of machine-polished, dancefloor-first Techno.
