Ice Nine Kills is an American post-hardcore band from Boston, Massachusetts. Formed in its earliest incarnation in 2006 by high school friends Spencer Charnas and Jeremy Schwartz, the group originally pursued a style combining pop punk, emo, post-hardcore and ska into their own innovative blend of rock but have since shifted into more of an experimental metalcore hybrid. Charnas is currently the only remaining founding member.
To date, Ice Nine Kills have released three full-length studio albums; Last Chance to Make Amends, Safe Is Just a Shadow, and The Predator Becomes the Prey and three EPs; The Burning, 2 Song Acoustic and The Predator. Their band name is derived from the fictional substance ice-nine from the science fiction novel Cat's Cradle by Kurt Vonnegut.
