Converge is an American metalcore band formed by vocalist and artist Jacob Bannon and guitarist and producer Kurt Ballou in Salem, Massachusetts in 1990. While recording their landmark fourth album Jane Doe in 2001, the group became a four-piece with the departure of guitarist Aaron Dalbec and the addition of bassist Nate Newton and drummer Ben Koller. This lineup has remained intact since. The members have also been involved in various side-projects and collaborations, including the bands Supermachiner (Bannon), Old Man Gloom (Newton), and Mutoid Man (Koller). With their extremely aggressive and boundary-pushing sound, rooted in hardcore and heavy metal, they are pioneers of metalcore and its subgenre mathcore.

Metalcore is a fusion genre combining elements of extreme metal and hardcore punk, that originated in the late 1980s. Metalcore is noted for its use of breakdowns, which are slow, intense passages conducive to moshing, while other defining instrumentation includes heavy guitar riffs often utilizing percussive pedal tones and double bass drumming. Vocalists in the genre typically perform screaming, more popular bands often combine this with the use of standard singing, usually during the bridge or chorus of a song. However, the death growl is also a popular technique within the genre.
