Chicago hardcore

Chicago hardcore experienced a mainstream crossover in the 2000s, when bands originating from the scene, including Rise Against, Fall Out Boy and the Lawrence Arms, received international success.

[6] By the end of the decade, bands including Arma Angelus, Racetraitor, the Killing Tree and Extinction were fronting this scene and touring nationally.

[7][8] Running parallel to the straight edge scene, but totally disconnected was bands on the South Side of Chicago including Los Crudos, Charles Bronson, Mob Action and Insult to Injury, who continued the faster, punk-leaning style of hardcore.

[10] Rise Against was founded, under the name Transistor Revolt, by former members of Arma Angelus, Yellow Road Priest, Baxter and 88 Fingers Louie, pursuing a more melodic take on hardcore.

[11] Fall Out Boy was formed in 2001 by members of Chicago hardcore groups such as Arma Angelus, Racetraitor, Extinction, and Yellow Road Priest wishing to pursue a more pop-centric and radio friendly sound.

Around this same time, former Racetraitor and Killtheslavemaster and future-Fall Out Boy drummer Andy Hurley, along with members of 7 Angels 7 Plagues and Vegan Reich, formed Project Rocket, a similar departure into more accessible music.
