Poison the Well is an American metalcore band formed in Florida in the late 1990s. The group became known for an intense blend of hardcore, metal and melodic passages, with songs that move between rhythmic aggression, emotional tension and more fragile atmospheres. With albums such as The Opposite of December... A Season of Separation, Tear from the Red and You Come Before You, Poison the Well became one of the most influential bands in metalcore and post-hardcore during the 2000s.
