Sarah Sey is tormented by her own demonic alter-ego, in Annie Harmeston's dazzling promo for the French singer. 

Evoking the retrofuturistic style of the early 2000s, the video for Ton Égo is a vibrant and conceptual vision, complete with shimmery art direction and killer styling. 

It's an ambitious feat, elevated by Sey's willingness to completely dive in to the role and Harmeston's obvious affinity for nostalgic pop culture moments.
