"Either be hot or cold. If you are lukewarm, the Lord will spew you forth from His mouth." Wise words from rock'n'roll's original hellraiser, Jerry Lee Lewis, and the kind of all-or-nothing spirit epitomised by Hedi Slimane's reset of Saint Laurent.
In a new series for the Saint Laurent Music Project, Hedi photographed three legendary icons of rock'n'roll and blues: Chuck Berry, BB King and Jerry Lee Lewis.
Shot in August and September as Hedi road-tripped through the South and Midwest US seeking out the heroes he's admired since his teenage years, all three wear specially-made Saint Laurent suits.
BB King, who once called blues the "mother of all American music", is shot on location in Las Vegas, wearing a Saint Laurent Le Smoking suit while holding his electric guitar.
Chuck Berry is photographed in St Louis, Missouri wearing a Saint Laurent Teddy tux, accessorised with his signature captain's hat.
Finally, Jerry Lee Lewis is pictured in a Teddy tux with his beloved piano, photographed in Nesbit, Mississipi.
The most straightforwardly 'rock institution' of the musicians shot thus far, there's nonetheless a direct line to be traced from these original hellraisers to the ride-or-die spirit of Courtney and Marilyn Manson. captured by Slimane in his earlier portraits.
Long before Love and Manson were specialising in outrageous acts and accused of glamourising drug use, Jerry Lee Lewis was branded for moral bankruptcy and Satanism; Chuck Berry once served two and a half years for armed robbery. And long before Ariel Pink and Christopher Owens had strummed their first A Major, BB King was running into a burning building to save his beloved guitar.
The images also serve as a reminder of the influence of blues on the very first Saint Laurent show, which was soundtracked by a Daft Punk edit of late, great blues musician Junior Kimbrough.
And beyond that, there's something to be said for knowing that teenaged Hedi Slimane's heroes were those who led the way in musical rebellion, individuality and gritty newness.
