Jacob Collier (born August 2, 1994) is an English singer, songwriter, multi-instrumentalist, producer, and educator. His music incorporates a combination of jazz with elements from many other musical genres, and often features extensive use of reharmonisations and close harmony. He is also known for his energetic live performances, in which he often conducts the audience to sing harmony or percussion parts.

In 2013, his split-screen video covers of popular songs, such as Stevie Wonder’s “Don’t You Worry ’bout a Thing”, began to go viral on YouTube. In 2014, Collier signed with Quincy Jones’s management company and began working on his one-man, audio-visual live performance vehicle, designed and built at the MIT Media Lab by Ben Bloomberg.

In 2016, Collier released his debut album, In My Room, which he recorded, arranged, performed and produced himself in the small back room of his family home in Finchley, North London. Collier is the first British artist to receive a Grammy Award for each of his first four albums.
