Trigger is a song by Swedish heavy metal band In Flames from their 2002 album Reroute to Remain.
A standalone version of the song was released as an EP on 10 June 2003, including bonus tracks.
The music video for "Trigger" showed the band playing in a club and being constantly pestered and booed by the members of Soilwork, with interspersed footage of other incidents between the two bands.
The colour is also reversed in each video: blue for In Flames, red for Soilwork.
While some believed the tension between the two bands to be real, in reality the groups are close friends and devised the idea of a dual-video concept as a joke.
