i admit i’ve been out of the production side of house/techno for years (and even when i was trying to make tracks, never really got into the engineering side of it) but weren’t pretty much all pre-DAW tracks written and produced without sidechain compression? i hadn’t even heard the term until a few months ago and never found any of the old school mixes to be muddy on the low end – the great ones are clear as a bell with bass and kicks.
