I was watchng a documentary about the guitarist and producer Nile Rodgers, who together with his musical collaborator Bernard Edwards had, with Chic and (as producer) Sister Sledge, a golden run of hits in the late 1970s, at the height of the disco boom. And then – after the so-called ‘Disco Demolition Night‘ in 1979’ – neither band had another hit. Without trying to overthink it this was a cultural moment that deserves a little more reflection.
