Put on MGMT’s ‘Electric Feel’ and close your eyes: you could be listening to the background music to a love scene in Miami Vice. And that’s a compliment. It is so resolutely 1980s, with its slap-bass, synth drums and soft rock keyboards, that it could be attending a march in support of striking miners. Yet it possesses a sleek, streamlined gloss and undercurrent of sauciness that is impossible to deny. The kind of song to which New York art dealers have threesomes.
