You can't just limit yourself to old school death metal because you don't like newer death metal. Influence is influence whether you like it or not. Obviously Death and Morbid Angel were influential, but you can't deny Suffocation and other's influence because you don't like the product.
I am not denying their influence but they are not the biggest infleunce on death metal nor is the NY scene. You come off so clueless and ignorant regarding death metal and metal in general. You are one of the few posters that does not really know anything at all regarding metal music.
