There is more than one artist with this name: 1) Formed in Boston in 1997, Isis is a band that combines ambience, atmosphere, and aggression to form a unique style of metal music. Isis draws from post-rock, which leans away from the traditional elements of choruses, verses, repetitive vocals, or fast/repetitive riffs. Compared to many post-rock bands, though, Isis displays more hardcore and sludge influence (especially in their pre-Celestial era).
