Ellise Shafer The past few weeks, Labrinth has been riding a high. Last month, the artist, producer and Emmy-winning “Euphoria” composer delivered the biggest performances of his career at Coachella. One of the most talked about sets of the festival, Labrinth surprised fans with special guests both weekends: Billie Eilish came out during Weekend 1 to sing their buzzy collaboration “Never Felt So Alone”, and the second weekend brought Sia and Maddie Ziegler for “Thunderclouds” as well as “Euphoria” star Zendaya, who hadn’t sang live since 2015 (when she briefly pursued a music career). Their rousing rendition of “I’m Tired” and “All for Us,” both songs from the hit HBO series, instantly blew up on social media.
