As a result, his roster of collaborators is varied and vibrant. Collier’s voice has been featured on recent songs from the likes of Coldplay, SZA, Stormzy, and Kehlani. In his own projects, Collier has worked with an unpredictable cast of artistic powerhouses, from Malian singer Oumou Sangaré to John Mayer, Shawn Mendes, Ty Dolla $ign, Daniel Caesar, and Tori Kelly.

Exploding onto the global stage with the viral success of his multi-frame, multi-instrumental YouTube covers, Collier caught the attention of the late Quincy Jones. Under Jones’ mentorship, Collier released his 2016 debut album, In My Room, which was played, recorded, and produced entirely by Collier.

Djesse (a four-volume album and his most recent project) has been a natural progression from the one-man process of In My Room, expanding to include collaborators from all over the world. The resulting volumes of Djesse have delivered on Collier’s ambitious promise, featuring an incredible array of artistic peers and musical themes that encompass everything from orchestral composition to folk songwriting, R&B, rap, and pop.

Collier concluded the Djesse “quadrilogy” with his final installment, Djesse Vol. 4,  released in February 2024. Djesse Vol. 4 encompasses 16 sweeping songs and a staggering list of special guests who all appear on top of the album’s connective thread and beating heart: a collective “Audience Choir” of 150,000 fans’ voices, which Collier recorded in seemingly every corner of the world.

Although Collier has already achieved more than most artists could hope for in a lifetime, he is still restlessly creative. He has plans for projects centered on solo piano, orchestras, film scoring, teaching, musical theater, and more.
