Emo violence or "emoviolence", also related to screamo and hardcore emo, is a subgenre of music that evolved from hardcore in the early 1990s, primarily in the Southeast of the United States - Florida in particular, (this can be seen on the Southeast Hardcore, Fuck Yeah!! compilation). This form of music uses vocals pushed past the point of normal sound by yelling and screaming, with occasional spoken words or singing. Emo violence is often poorly recorded to give it a foggy, low-fidelity sound.
Emo violence is the direct link from emo to screamo through reprocessing of influences. The term was originally coined by the group In/Humanity as a joke in reference to their own band and friend's bands Palatka and End of the Century Party. The tongue-in-cheek genre descriptor was a play on other meaningless genre descriptors of the time: (namely emo and power violence). In/Humanity claims that the phrase actually comes from the song "Emotional Violence" by the funk group Cameo.
