I was thinking, correct me if I'm wrong, but I think that only innovator music make success, I'm not talking about fame and money, but have you think about this? Why these new old-school bands are different, they present the same sonority, what make the original bands superior. The best answer for this, is what the innovator bands are better. The new musicians aren't make a modern sound, if are, are going really far, like Slipknot and Avenged Sevenfold, they create a modern sound, but isn't what we hessian want. Where are our actual Morbid Angel, our actual Burzum, out actual Paradise Lost. This answer why listen these new black metal bands are so boring, the musicians aren't creating a good modern sound, they are making a exactly copy, I'm not talking about the new black metal, but i consider they a little boring too.
Black metal, death metal and grindcore was good before over, we can go on, you can have influences but these genres are dead.
Where are our innovators musicians?
