Killswitch Engage

Killswitch Engage is an American metalcore band formed in 1999 in Westfield, Massachusetts. The group was created through the merger of members from two previous projects, Overcast and Aftershock. The original lineup consisted of vocalist Jesse Leach, guitarists Joel Stroetzel and Adam Dutkiewicz, and bassist Mike D'Antonio.

The self-titled debut album Killswitch Engage was released in 2000. The band gained international recognition with their second album, Alive or Just Breathing (2002), which is often considered a landmark in modern metalcore. After its release, there was a change in the vocal position—Jesse Leach left the band and was replaced by Howard Jones. With Jones, the band released the successful albums The End of Heartache (2004) and As Daylight Dies (2006).

In 2012, Leach returned to the band and has since continued to perform and record with them. Other notable releases include Disarm the Descent (2013), Incarnate (2016), and Atonement (2019). Killswitch Engage's music combines elements of melodic death metal, hardcore, and traditional heavy metal. Their lyrics focus on personal themes, resilience, inner struggle, and human relationships.
