Nat you hit the nail right on the head. Especially on Converge that band might have one of the biggest split opinions in all of metal.
As someone who has seen Mastodon live 3 times i will say they are great live when Brent Hinds isnt drunk. The only thing thats bad about Mastodon's live show is their stage presence which they have none of.
