After Overcast broke up in 1998, bassist Mike D'Antonio jammed with Aftershock guitarist Adam Dutkiewicz . Dutkiewicz, now playing drums, recruited guitarist Joel Stroetzel from Aftershock and vocalist Jesse Leach of the band Nothing Stays Gold (who were signed to a record label owned by Dutkiewicz's brother Tobias, who was also the vocalist in Aftershock) to form a new band, Killswitch Engage . The band's name is derived from an episode of the television series The X-Files entitled "Kill Switch", written by William Gibson, who gave the episode this title after meeting the industrial band Kill Switch...Klick . </P> <P> In 1999, Killswitch Engage recorded a demo containing four tracks, including "Soilborn", the first song written by the band . The demo was first released at the band's first show, opening for melodic death metal act In Flames, in November 1999 . They released their self - titled debut album the following year . Although initially the album was not a financial success and did not land on any charts, it attracted the interest of Carl Severson, who worked at Roadrunner Records at the time . Severson handed Killswitch Engage to several Roadrunner representatives . Mike Gitter, a talent agent of the company, contacted D'Antonio, attended several of the band's shows, and offered the band a recording contract with Roadrunner . Realizing that Roadrunner had the resources to promote and distribute Killswitch Engage releases, the band accepted his offer, declining several offers from smaller labels . </P>
