Decibel I believe, here's the article...
"Because the Top 20 Nü-Metal Guitarists was too hard to whittle down...
Determining the 20 greatest death metal guitarists of all time was an appropriately brutal, bloody and chaotic process. In its initial planning stages, this was to be a list of the 10 greatest death metal guitarists of all time. But then the IMs and emails started flying back and forth among Decibel’s editorial staff: What about so-and-so? That guy over this guy? What the fuck do you mean, “overrated?” Cases were made. Feelings got hurt. The fact that any of us have girlfriends was regarded with solemn wonder. Ten guitarists became 20. Finally, we have a list that’s 100% guaranteed not to please everybody. Which is kind of the point: Death metal, as maligned as it is (it all sounds the same, you can’t understand what the guy is saying, Cookie Monster, blah blah et cetera), offers up enough diversity and has so many accomplished, often visionary players that making this list was fucking HARD. At first glance, there’s not much common ground between Baz Thompson’s monolithic chugging and Muhammed Suiçmez’s impossible über-shredding, or between Opeth’s Mikael Åkerfeldt and grindcore riff-factory Scott Hull. What all of our picks do share, whether they’re self-taught or classically trained, dedicated to progression or happy to pay tribute to their metal guitar heroes, is a discipline and devotion that we’ll put up against any other genre any day of the week. Given another few weeks and a mediator to keep things from getting violent, we probably could have stretched it to 40.
