From producing Warm Leatherette, to founding Mute Records, few people have done more for electronic music than Daniel Miller, a genuinely legendary figure in modern British music. His improvisational electronic duo, Sunroof, have a new album out in February and he was playing live and DJing at the recent Ombra festival in Barcelona, which is where I caught up with him to talk analogue synths, being on his own label, Kraftwerk, the appeal of synths, punk, Depeche Mode and being indie in 2022.
