Chaos A.D. was the first Sepultura album that I heard. The first time I heard "REFUSE/RESIST" my jaw dropped to the floor. The groovy heavy riffs blew me away, and more importantly; Max Cavaleras angry fucking vocals just grabbed me by the balls and didn't let go. I was addicted to CHAOS A.D for a good portion of my sophomore year of high school(2004/2005). I thought it was the greatest thing ever made, and i loved every track except for "Territory". That all changed once I heard Beneath the Remains, Arise, and Bestial Devastation..
Still, it's a good album, and BIOTECH IS GODZILLA is probably in my ten favorite sepultura songs ever.
