A few years back, you couldn’t go to a club without seeing a “Rave Strikes Back” sticker on a DJ’s record box. An initiative set up by Freude-am-Tanzen, the idea was to revolt against the ahistorical “mnml” of the time and bring back “rough, unpolished techno,” in the words of its creators. On the website, they invited a number of Germany’s pre-eminent DJs (Robert Johnson’s Ata, Michael Mayer, DJ Koze) to chart their favorite rave anthems. Superficially, the planned revival appeared to have little tangible effect, save the unconnected splutterings of a D.O.A. scene in the less salubrious parts of south-east London (thanks, Klaxons).
