I was really into metal once upon a time. I've expanded my tastes since then, but at one time I was deeply into the scene as it was. Was even the front person of a band with a following (We were called Ravager)
I've always been into the old school quite a bit more then newer styles (Maiden, Sabbath etc) and into the more underground sub genres (doom, thrash, early 90s death scene, black, power)
The newer metal bands that I like are on the more progressive side of things, and are almost jazz/jam metal at times. Do yourself a favor and look up Hypnos 69 Legacy full album on youtube
