Guys. Please. i imagine Linkin Park and the emo community would both be upset.
Emo is Thursday. Emo is The Get Up Kids, and sometimes Jets to Brazil, and maybe a little bit of Alkaline Trio, if they're feeling particularly down; emo is whatever solidified back with Fugazi and exploded into the hardcore scene on this whole new concept of dramatic melody and introspective vocals and generally a lot of silliness. Though there are, i'll admit, plenty of great emo acts.
Chester wears thick black glasses and sings about himself. Similarity done. i can understand the association, but they're just too much post-grunge metal sludge.
Plus, emo likes to kick out the big ones.
