who is the "The Heaviest Metal band Ever"

If you want to hear some of the heaviest stuff ever!!! , you need to check out some of

Gorgoroth
Brain Drill
Beneath the Massacre
Behemoth
Cannibal Corpse
Skinless - (NOTE: the lead singers Death growl is Shocking, may cause traumatization)
Deicide - (For those who listen to Death Metal, and yet are still Christian, some of the lyrics may be offensive)
Belphegor - same as above

Motorhead and Deicide are my personal faves.
Pretty good taste flows through this thread.

Wow you people don't know what heavy means do you? Heavy doesn't mean politically inspired, meaningful, or intelligent. It means distorted, fast paced, thrashy music. I will help you out.

Chelsea Grin
Thy Art Is Murder
Bring Me The Horizon

Three of my favorites. KEEP IN MIND THESE ARE AQUIRED TASTES. Most people don't have open ears for it.
