I, Barbarian

It has shades of and  influences with Max's guttural vocals sounding like the kidnapper from  movie, said schuler reviewing the album on Encyclopaedia Metallum. It has guitar solo before ending the song. The title of the song was taken from Max's autobiography. A review on Rock Revolt Magazine says, "Thrashy, wild and carnal, “I, Barbarian” atavistically spreads through every thread of human fiber in your being, and shreds them back to a more primitive and savage epoch."

The video shows the live group performance as well as clips from the 2014 film. The old vintage film effect was made using Adobe After Effects.

Lyrics
Blood soaked on the ground I hear the thunder sound Mercy cannot be found The coliseum roars

This is your scorn This is your bones tored This is your blood flows This is the fall of Rome

I, Barbarian I, Barbarian

Devils come out to fight Surrender or survive Under the black sky Can you stay alive?

Prepare to meet your maker Disguised asunder taker Don't break the final oath Murder your soul at dawn

I, Barbarian I, Barbarian

Kill at will... Will to kill... Kill to thrill... Thrill to kill...

Kill... Kill... Kill... Kill... Kill...
