Disco started to go mutant before the backlash of 1979 compelled its producers to quit their exploration of punk, new wave, funk and dub combinations. As disco outsold rock for the first time during 1978, for instance, figures such as Arthur Russell, Michael Zilkha and Walter Gibbons were carrying dance music into dissonant territory as they added their left field touch to releases like Dinosaur’s “Kiss Me Again,” Cristina’s “Disco Clone” and Love Committee’s “Just As Long As I Got You.” But the shake-up arguably started even earlier, when Grace Jones recorded “I Need a Man,” “Sorry” and “That’s the Trouble” for the French label Orpheus between 1975-1977. Admittedly, Jones didn’t set out with any radical intent, her main concern being to switch from modelling to music. Yet these releases stand out as early studies in disco juxtaposition thanks to the way her stiff, gravelly voice combines so uneasily with the standardized disco-backing track. DJs and dancers could start to freak out in a different way.
