Electron Sheep began in 2001 as a one-man band led by Lee Jong-bum and now performs as a four-piece with Jung-Mok, Ryu Ji, and Sol-ki. With their early albums Day is Far Too Long and Forest, the band established a singular musical identity that earned them the nickname “the kings of basement indie pop.” Since then, Electron Sheep has built a devoted following through distinctive songs with denser, more solid soundscapes, including tracks such as “King of Noise” and “Dungeon.” In December 2025, they released their fourth full-length album Play & Work, their first in eight years, capturing the present state of a band for whom playing together has gradually become part of everyday life. Through touring and live performances, Electron Sheep continues to deepen and expand its unique sonic world.
