I believe it's Meshuggah. And god bless you. Swedish metal in 11/17 time for all!
DX: Apparently, Opeth are going to get even heavier with their next album. I heard so on the Lamentations DVD.
See, Opeth have found a loophole in the "Sold-out" system. They can put out DVD's, sell half a million records, and play big venues, but the fact that they are a death metal band alone makes sure that they will never recieve radio-play(other than Dr. Insano), and due to their song length they will never have a music video.
A winner is Opeth.
I doubt Opeth could ever become truly metal, but as it is, they have tons of sales, and some of the highest attendance in true metal.
Just because you sell out doesn't mean you've sold out ;)
Also, I disagree with the branding of "death metal" for them. Too melodic and artsy for death metal. I'd say doom/black.
