I love death metal, a bit of black metal, tons of thrash metal and lots of grind, gore and goregrind and, of course, most old school heavy metal.
Among my favorite bands are;
Morbid Angel, Carcass, Napalm Death, Death, Deicide, Bathory, Atheist, Kreator, Exodus, Pungent Stench, Prong, Voivod, Nocturnus, Entombed, King Diamond (his 2008 USA tour has been cancelled and that hurts me way more than it probably should).
Some other bands I either just now got around to loving or are newer: Mekong Delta, Orange Goblin, Anaal Nathrakh, Ackercocke, Autopsy, Wormed, Insect Warfare, Gorerotted, Death Breath, Necrophagist, Immortal (and Abbath's side project I), Dying Fetus, Nailshitter, Meshuggah, Aborted, Pig Destroyer, Devin Townsend (The Ziltoid album kills me - I don't know why it took me so long to stumble across Devy), Death By Dawn, Lock Up, and tons more...
I like that y'all started a metal thread because when I'm not jamming to Led Zep, this is what I do. Zep was my first and favorite band but they led me to all these other kinds of music.
