I went through various forms of metal like many others do. If I recall correctly, I bought my first album, Appetite for Destruction, by Gun's 'n' Roses, at age eight or nine. From there, I got into Iron Maiden, Megadeth, Slayer, Anthrax, Exodus, Suicidal Tendencies, and the like, pretty much all the major basic metal and thrash bands of the late 80's and early 90's. I continued to listen to metal in junior high school, but then came across a weirdo punk-turned-White Power skinhead in gym class who rattled off a bunch of bands in the death metal, hardcore punk, and thrash genres. So from then on I got into both death and hardcore bands: Death, Morbid Angel, Carcass, Entombed, Dismember for death metal, and Agnostic Front, Exploited, Discharge, Sick of it All, old Black Flag, Minor Threat, and the like for hardcore. This was in the early 90's and CB's still had the matinees on Sundays. I said no thanks to his invitation because fighting, gangs, and graffiti writing were not my things, but I continued to listen. Then I got into harder thrash, like Sodom, Kreator, Dark Angel, and so on. And then when that made its mark, I moved onto some black metal, like Darkthrone, Mayhem, Graveland, and so on. That shit can get corny, but some of it is great. Plus a lot of it is National Socialist (e.g., Thor's Hammer, Goatmoon, Satanic Warmaster), which is a bit much for most people, but whatever, some of the bands are very good.
I saw Morbid Angel live. It was great.
