Since 1999, Killswitch Engage has been widely recognized as one of the bands that helped propel metalcore into the mainstream with its 2002 album, Alive or Just Breathing. That very same year, however, lead vocalist Jesse Leach decided to part ways with the group rather unexpectedly, leaving the rest of the band scratching their heads.
“At first it was very awkward when Jesse left,” said Mike D’Antonio, who plays bass. “But we’re pretty easygoing guys. We were going out to see his band, and he actually sang on a bunch of our records. There were no hard feelings.”
