British musician who serves as the enigmatic lead vocalist of the progressive metal band Sleep Token, performing under the stage name Vessel. Known for his distinctive masked performances and dynamic vocal range that seamlessly transitions from soft, melodic singing to intense screams, he has become one of the most intriguing figures in modern metal music.

He grew up in Bristol and began his musical journey at a young age, studying at the Bristol Institute of Modern Music. Before achieving widespread recognition with Sleep Token—which was formed in 2016—he was involved in various musical projects including a solo project called Dusk and the ambient duo Blacklit Canopy with Gemma Matthews.

Sleep Token’s unique blend of alternative metal, progressive metal, and post-rock has garnered critical acclaim and a devoted cult following. His proficiency extends to piano and guitar in addition to his exceptional vocal abilities, instrumental in shaping Sleep Token’s distinctive sound. The band maintains strict anonymity, with all members performing in masks and robes.

Leo George Faulkner maintains a highly private personal life, consistent with Sleep Token’s emphasis on anonymity. He is based in the United Kingdom and has kept details about his family background confidential to preserve the mystique of his Vessel persona.

Sleep Token has toured with major metal acts and performed at prominent festivals worldwide. The band’s mysterious approach to identity has drawn comparisons to artists like Ghost and Slipknot, who also incorporate theatrical elements and anonymity into their performances.
