Marduk are awesome because they dont use distortion on their vocals like Dimmu and cof. And they have one of the most craziest drummers. As for Immortal, UHHHH! I never liked them. Mayhem is pretty good but not quite really fast with blast beats but its a good example of what old school BM is all abot. Possesed and Bathory are one of mine and my brother's favorite old BM bands.
