I voted for Venom, because...Black Metal is up their on my list of favorite classic heavy metal songs. My second choice is prob Mercyful Fate, than Slayer. I haven't really been listening to alot of Priest, Maiden, or Sabbath. Not to mention Megadeth >>>>>>>> Metallica...
I voted Metallica, they were the band that got me into so much great music so they still hold a special place in my heart haha cheesey aye!!!
Close 2nd would be Sabbath though..
