One of the first items you see upon entering the Design Museum’s ambitious new history of electronic music is a vast Andreas Gursky photograph of ravers in Dusseldorf in 1995. Electronic debuted at the Philharmonie de Paris last year and this expanded, anglicised version was meant to open in April, but subsequent events have rendered the curators’ efforts to represent electronic music’s fans as well as its practitioners unexpectedly poignant. A scenario that was commonplace for 30 years is suddenly unattainable: a sweaty paradise lost. Social distancing hasn’t just changed the layout of the exhibition but its emotional resonance. It’s just a shame that there’s no mention of masked rave duo Altern-8 now that every museum-goer resembles them.
