No Trigger is a melodic hardcore band from Massachusetts, United States. The band formed in 2000, with a sound which takes cues from like-minded outfits such as Strike Anywhere and None More Black. The band self-released two demos, one of them a split with Wasteland. By this point the band had started to gain accolades from the webzine likes of Pastepunk and Punknews, the latter of which referred to No Trigger as close to being "the best unsigned band in America".

In late 2004, the band compiled these recordings and remastered the sound for their debut release, Extinction in Stereo, released on independent record label Bigmouth Japan. Extinction received a significant amount of attention and praise from the punk rock press.
