Donna Summer will be remembered as the queen of disco, but in fact her best records transformed not just dancefloors but the course of pop music. Released in 1977, the year of punk, her single
I Feel Love was as radical as any record that has got to No 1. Sparks were a glam rock band until they heard I Feel Love, when they decided to throw their entire musical direction in the dustbin and make pulsing, synthesised disco records with its producer,
Giorgio Moroder. Seeking to assert his credentials as a man of impeccable musical taste, Bobby Gillespie of Primal Scream used to boast that he had bought both I Feel Love and the Sex Pistols' God Save the Queen on the same day. The combination of silvery female soul vocals with state-of-the-art electronic production, which has been responsible for some of pop's greatest and most groundbreaking singles, from Janet Jackson to Aaliyah to Beyoncé, was pioneered right there by Summer and her two Italian producers - Moroder and Pete Bellotte.
Working from the unlikely location of Munich, the trio managed to fuse soul with the surgical precision of Kraftwerk, creating a record so far ahead of its time that pop took a good 20 years to catch up. Like the Beach Boys' Good Vibrations, I Feel Love is a studio recording so perfect that covering it – or even playing it live – would be pointless, though many have tried. The sparsest ingredients – lyrics that could be written on the back of a beermat with room to spare, a bassline that, in theory, a three-year-old could play – are turned, in Summer and Moroder's hands, into an entire world of futuristic wonder. Moroder took a Moog Modulator synthesiser and put a delay on the bassline, creating the "dugga-dugga-dugga" sound that has galvanised dancefloors ever since. Summer's vocal is no less wonderful – ethereal and otherworldly.
