I just finished watching Get Thrashed. It's a documentary about the history of Thrash Metal. It was pretty good. I'm kinda late to the thrash scene so it had a lot of info I didn't know. Thrash started in like '82-'83 when I was 4-5 years old so you can understand that I wasn't a metalhead back then. All I heard was Sharon, Lois and Bram or the country crap my Mom listened too. I got some CCR and stuff like that from my Dad, but it wasn't metal. I didn't get into metal til "One" by Metallica and even then, I wasn't INto it. I hadn't denounced everything else yet. (Sepultura did that for me) Of course, I got into the Big 4, had no idea about Exodus, Testament, Kreator, Death Angel, etc etc. I have heard of them before this but didn't really know the history or how they fit into it.
If you are into metal at all, I highly recommended this doc. Great music, great insight. It's different than Heavy Metal in Baghdad because it's not just about one band. It's not quite as good as Metal: A Headbanger's Journey, but better than that one Penelope Spheeris did. The Decline of Western Civilization 2: The Metal Years. I might even say it's better than Global Metal. The sequel to Headbanger's Journey.
I really dig documentaries on stuff I like. And I love metal.
