Stromae is back. After teasing his return on Instagram a few days ago, the Belgian artist has shared a new single titled “Défiler (Bande originale de la capsule No. 5 Mosaert)." The sprawling nine-minute track was composed with his brother Luc Junior Tam. The song soundtracked Belgian label Mosaert's first ever fashion show at Le Bon Marché in Paris, which you can watch below.
