Baroque pop and experimental singer-songwriter Scott Walker and pop singer extraordinaire Sia have been tapped to compose the original soundtrack for Vox Lux, a Brady Corbet directed film which will be premiering at the Venice Film Festival later this September 4th, and then air at the Toronto International Film Festival three days later..

The movie is apparently a musical which stars heavy-weight talents including Jude Law and Natalie Portman. Vox Lux will tell the story of a fictional singer Celeste, portrayed by Portman, and, starting in 1999, fifteen years of the protagonist’s artistic career as she makes her way to fame.

This will not be Scott Walker’s first go at scoring a film either. In 1999, he scored the unclassifiable Leos Carax’s romantic drama “Pola X.” And just three years ago in 2015, he edited the soundtrack of (also) Brady Corbet’s “The Childhood of a Leader,” a film which covered (unsurprisingly) the childhood of a fictional fascist leader. With Walker having provided incredibly tense, atmospheric soundtrack for the latter, there is much to expect from this new film’s soundtrack.

Prior to this gig, both artists have been relatively busy. Sia has been continuing her work with supergroup LSD, in which she performs alongside electronic artists Diplo and Labrinth, with their last single “Thunderclouds.” Walker has just published a book titled “Sundog,” of his avant garde lyrics that have spanned across what is now a six decade long career.
