Giorgio Moroder has achieved a great many things in his 73 years on Earth. He practically invented electronic music, pioneered synth disco (Donna Summer’s ‘I Feel Love’ being its electro-shocked jump-start), influenced the development of techno, scored some of the most defining films of the 80s including Flashdance, Scarface and that one with the big flying dog. He also grew the most knee-weakingly terrific moustache, won three Oscars and helped rescue and restore one of the single most important works of cinema, the Great-Granddaddy of dystopian dramas... the mighty Metropolis.
