>>81888148MCR is alternative, leaning on emo/screamo, all depending on their album since you can easily make the case of emo for Black Parade and maybe Three Cheers, but their sound differs heavily between more of the lighter screamo of Bullets or more of the alternative experimentation of Danger Days. That's also not to mention anything to do with Conventional Weapons, or their return to form with The Foundations of Decay.
