Hey dude I've seen Sepultura! And that's really cool someone else has too. They opened for Black Sabbath (with Ozzy, I've seen Sabbath 3 times.. once with Martin and once with Dio, too). Before them was Morbid Angel.

Morbid Angel, Sepultura, Black Sabbath. This would've been 'about' 1994. Great times!! Thanks for sparking the memory.
