youve just repeated what progressive metal is as dream theater and symphony x are both progressive metal bands secondly if its a genre give me a musical definition of it rather than random traits and bands copied from other articles about other genres as it stands this genre is a fusion between alternative rock and metal thats all well and good except most all the bands that fit here are nu metal bands almost all the description given here has been of nu metal bands i suggest to aj wesleydodds that he gets cracking with the editing of the articles otherwise i will start a merge at the end of the week
