Slipknot sound nothing like Dimmu Borgir, Corey and Shagrath's screams are worlds apart and Galder/Silenoz's technicality and coordination far surpass anything Slipknot has done guitar-wise. Lastly, if you bothered to take a good look at what DB really is, you would see that Vortex handles clean harmonized vocals like no one else, he is superb. I don't see any of that in the talentless Slipknot. Those two bands are completely different and the reasons they are are almost endless, so I won't go on and on. Now please, go fall on an icepick and make the world a better place.
