Schranz is hard, fast, abrasive German techno named onomatopoeically, associated with Chris Liebing since the late 1990s

Schranz designates a strain of hard, fast, banging techno with a scrapy, dirtily abrasive sound; Reynolds reads the name as German onomatopoeia for that abrasive texture. The term has existed since the late 1990s as a local-to-Germany label associated with DJ/producer Chris Liebing, and only gradually crept toward wider currency without ever fully breaking out. Reynolds notes he found a Chris-Liebing-associated album (Metalism) still convincing despite being over 20 years old — an illustration of the same atemporality he diagnoses elsewhere.

Examples

Chris Liebing’s Metalism-era hard techno as a reference point for the schranz sound; contemporary reels of DJs playing ‘hard as nails’ techno to big rooms under the schranz banner, decades after the term was coined.
