In the late 2000s, Parisian duo Justice found themselves in an odd place. With the release of their debut album, which distorted France’s beloved house music almost beyond recognition, the band were thumbing their noses at the conventions of dance music while simultaneously becoming part of its firmament. Case in point is this mix, which, as the lore goes, was intended to be Justice's contribution to the vaunted Fabric mix series—commonly considered a signal of an artist's ascension to dance music’s upper echelon. The other part of that lore is that the set was so unconventional—so un-house, so un-techno, so un-breakbeat—and so short that Fabric rejected it. So Justice’s friends at Ed Banger Records put it out as a promo mix. Whether or not you buy the story, you can understand how it got its legs: The mix kicks off with glam provocateurs Sparks’ pseudo-disco track “Tryouts for the Human Race” (produced, of course, by Giorgio Moroder), carries on through The Korgis’ dream-sequence ballad “Everybody’s Got to Learn Sometime” (with the occasional diversion into actual dance music), on to the spacey French rock of Julien Clerc and Daniel Balavoine, and ends with a suite of full-on prog from The Fucking Champs, Todd Rundgren and others. A deep-cut collection of mostly ’70s and ’80s treats was hardly what folks had come to expect from Justice at the time, but it keenly reflected where they were going next: to the prog-rock fantasies that would define their 2011 LP, Audio, Video, Disco.
