For a duo who - at their inception - sounded like they were channeling the carnage of the universe's most exclusive intergalactic club, it's a substantial shock to the system to hear that somewhere in the 5 year gulf between their debut Cross and their new opus Audio, Video, Disco, robots have become rockstars. There was always a certain degree of grinding industrialism and punishing riff-mongering in Justice's darker moments, but this is an entirely different beast. Almost as if Gaspard Auge and Xavier Rosnay have been holed away in a dingy, smoke-filled basement somewhere swigging straight Jack Daniels and blowing the dust off copies of everything from Motorhead to Yes, the Parisian club magnates have burst out of their oeuvre in a hail of scalding rock riffery, pounding drums and incendiary guitar solos.

Much will be made of Justice's new affinity for cacophonous riffs and hair-metal drum breaks, but at the root of it 'Audio...' lies a very similar beast. Whether armed with gut-wrenching synthesizers or squealing hair-metal guitars, the duo undeniably know their way around both hook and melody, and in this sense, little has changed between the two albums. The duo, time-travelling aside, appear as meticulous as ever in their construction, only this time interweaving guitars round their erstwhile electronics.The throbbing intensity of old favourites like 'Genesis' and 'Waters of Nazareth' still lives and breathes in the tumultuous 'Horsepower' and the jerky 'Helix', albeit outfitted with a few extra studs clad in their previously pristine leathers. The pop sensibilities are still there as well, 'Newlands' is 'DVNO' re-imagined via Boston's 'More Than a Feeling', whilst the now-familiar release 'Civilization' makes 'D.A.N.C.E.' look like a timid pop number in comparison to its unflinching bombast and stadium-rousing hooks.

Justice never did small, per se, but on 'Audio...' its a whole new zenith; as if every moment, every unflinching breakdown and synergy between broken electronics and screaming guitar is designed to fill every inch of the largest arena on earth. Sometimes moments like the Van-Halen baiting neo-classicism of 'Brianvision' borders on the ridiculous, but the whole effort is thankfully imbued with such self-knowing absurdity that these trilling hair-metal moments sit comfortably alongside the sincerely crafted weight of 'Canon' or 'On'n'On' with little to criticize.

There are few acts that could take five years out of their career and return with all their best qualities intact and redressed in such a dramatic way; not as the reigning champions of electro -, but instead re-styled as the tongue-in-cheek Monsieurs of rock, yet on Audio, Video, Disco, Justice achieve a difficult feat, breathing new life into their inimitably successful formula in the most unlikely, unexpected and exciting way. The undeniable sense of fun at work definitely anchors an evolution that runs the risk of sliding into the ridiculous at any second, but after a single listen through the grandiose pomp of Audio Video Disco, it's easy to see it's time to raise your Jack Daniels, light your cigarettes and throw your rock hands high for the triumphant return of dance music's most enigmatic magnates.
