What metal is the heaviest? Who wears the crown?

Right now, I say the crown goes to High On Fire...their new album is amazing. They are way heavier than Lamb of God, or any of the newer crap coming out now. Mastodon is also an awesome band.... VERY heavy.

The heaviest band playing right now is Lamb of God. They're brutal!!! Older bands that are some of the heaviest are Cannibal Corpse, Pantera, Slayer, Mettalica

Led Zeppelin Are **** & Deep Purple Is Rock

Black Sabbath

Judas Priest

Iron Maiden

Megadeth

Machine Head

Nothing Too Recent I Would Say Is Heavy

The heaviest metal by far is Grindcore metal.

Pantera

I'm not sure if they're the heaviest, but Opeth is a progressive death metal band, so I say it's pretty heavy (and awesome!)

Iron Maiden

Pantera is definitely one of the heaviest.

If you're looking for old school slower/softer stuff... go Sabbath or Metallica... but if you're looking for Death-metal face-melter music, then I suggest Slipknot or Mudvayne.
