Which other music groups can you see in KF2?

I'm not putting it in the Idea & Suggestions -yet- because I want some refining and additional suggestions.

Since the beginning I've thought that Trivium would be a great addition because of their Melodic-Trash-Death Metal style. It's really catchy and the lyrics/guitar play fits the atmosphere, I believe. It's not as aggressive as Living Sacrifice but it's in the genre of Demon Hunter.

I've made a small collection to give you some examples.

TRIVIUM

A Grey So Dark

Caustic Are The Ties That Bind

Drowning in Slow Motion

Inception of The End

No Hope For The Human Race

To Believe

Strife

Black

No Way To Heal

Dusk Dismantled

A Skyline's Severance

At The End Of This War

Watch The World Burn

Shattering The Skies Above

In Waves

As I Am Exploding

Incineration: the Broken World

Villainy Thrives

Through Blood And Dirt And Bone

Brave This Storm

Slave New World

Vengeance Falls

What do you think? Another group/song you think could fit with KF2?
I don't want ''Meh I don't like the songs in KF2 anyway, I prefer to disable it and put some dubstep instead''. I'd like some propositions that would fit with the existing tracks in the game.
