Sleep Token

Sleep Token are an anonymous English rock band formed in London in 2016. They have released four studio albums, two EPs, two standalone songs, and multiple covers.

The band consists of two main members, only known as Vessel and II. Live, they are joined by five touring musicians: bassist III, guitarist IV, and a trio of backing vocalists known as Espera. The members have never revealed their real names or identities. On stage, they conceal themselves with masks, long robes, and black body paint.

After self-releasing their debut EP, One, in 2016, the band signed with Basick Records and issued a follow-up EP, Two, the next year. The group signed with Spinefarm Records and released their first full-length album (LP), Sundowning, in 2019, which was followed in 2021 by This Place Will Become Your Tomb. A third album, Take Me Back to Eden, was released in 2023. Their fourth album, Even in Arcadia, was released in 2025 through RCA Records.
