The band structure consists of permanent core members Vessel and II, who handle all studio recordings and songwriting, alongside touring members III and IV who contribute to live performances. Additionally, the backing vocal trio Espera provides live harmonic support during performances. Sleep Token has received recognition through Heavy Music Awards nominations and wins, while maintaining their theatrical commitment to anonymity despite achieving mainstream success across multiple continents.
