Slipknot? Anders couldn't sound like Corey Taylor if he tried, which is good, becuz Coreys voice is SHIT. If u mean the guitars, then yes they sound a LITTLE like them, but the solos still sound of perfect In Flames quality. I'm betting part of the reason for this change is Bjorn and Jesper now using Gibsons fulltime instead of ESP guitars and changing their rigs up. If that's what you mean (distortion) by 'sounding like Slipknot'.
Don't get me wrong, Slipknot suxks balls cuz they don't do justice to their sound. In Flames does and pulls it off very good. The thought didn't even enter my mind about them sounding like In Flames when I heard Watch Them Feed, and it still doesn't because In Flames does NOT suck. Slipknot's drums are totally different, the guitar company (BC Rich) is different, Corey sucks, and.... yea so there...
In Flames does NOT = Slipknot
