Well, there you are then. No. I meant Heavy Metal not some sub genre that focuses on one tiny aspect of musical expression.I haven't read the whole thread and so I'm not sure what you're getting at. There were lots of metal bands in the early 90s, some of the main waves include the death metal explosion, the norwegian black metal scene, and the "groove metal" style headed by Pantera.
I say this because I believe 'Grunge' is nothing more or less than the next progression in actual heavy metal. That is the greatest compliment I can give to those who are or were part of that scene.
I don't believe 'Grunge' is any more significantly different from New Wave of British Heavy Metal than NWOBHM is from bands like Sabbath. So I'm not a big fan of denying it's pretty illustrious pedigree.
