Boris are an experimental Japanese band that formed in 1992 when members Atsuo, Takeshi and Wata met during art school.

Boris are prolific in their music's ambiguity when it comes to assigning them a musical genre, drummer Atsuo said in an interview,

"In the studio, our sound informs us. Also, sound and my consiousness and unconsciousness interfere with each other, and afterwards, the theme of the tune appears. Having some kind of preconceived message or theme is very boring to me."
