Underoath

A Christian band that is from Florida. Even if it may be emo, though emo can be classified a million different ways, it's still heavy. Really, EMO is what the singer sings about rather than what his voice produces and guitars, etc.

Their newer music is shit.

Underoath is badass!

Undertail

Another universe for the hentai-filled game: Undertale. It is under the tail which is an asshole and it's basically furry hentai.

Undertail is hot as fuck.
