Aftershock was a metalcore band based out of Boston, Massachusetts. The band was formed in 1992 by the Dutkiewicz brothers, and broke up in mid 1999 shortly after Adam Dutkiewicz joined Killswitch Engage. After a 2-year hiatus, in 2001, the group re-formed for a reunion tour in Japan. After the band's last effort, the release of the "Live In Japan EP" in 2004, the group officially broke up. The band also consisted of past and present members of Killswitch Engage and Shadows Fall.
