Converge is an American hardcore punk band formed by vocalist Jacob Bannon and guitarist Kurt Ballou in Salem, Massachusetts in 1990. During the recording of their seminal fourth album Jane Doe, 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. They have released nine studio albums, three live albums, and numerous EPs. The band's sound is rooted in both hardcore punk and heavy metal, and they are considered pioneers of metalcore as well as its subgenre mathcore.
