This is a list of bands that have played screamo at some point in their careers.
Screamo is a music genre which predominantly evolved from emo, among other genres, in the early 1990s. The term "screamo" was initially applied to a more aggressive offshoot of emo that developed in San Diego in 1991, which used usually short songs that grafted "spastic intensity to willfully experimental dissonance and dynamics." Screamo is a particularly dissonant style of emo influenced by hardcore punk and uses typical rock instrumentation, but is noted for its brief compositions, chaotic execution, and screaming vocals. The genre is "generally based in the aggressive side of the overarching punk-revival scene, although the term can be vague. The genre was pioneered by bands like Heroin and Antioch Arrow.
A typical emo/screamo fan will find this to be standard fare, but those looking for a more palatable foray into technicality should check out The Fall of Troy or Thrice.
The intensity and emotion put into these songs gives it an edge over most bands in the screamo category and it really helps define Circle Takes the Square as a band.

...To The Beat of a Dead Horse ... is solid contribution to the West Coast punk and hardcore scene as Touche Amore transcend several sub genres [sic], ranging from screamo to post-hardcore.
Four albums in, they're also taking the business of being in a band very seriously too, demonstrating a greater command of dynamics and a certain measure of professional panache, something adolescent, an adenoidal rush of their early screamo.
