I love metal-rap (and metal period).
I liked Heavy Metal of the 70s-80s also...
I kinda dropped out in the 90s cause it didn't sound as good anymore.
I saw these great bands:
Iron Maiden
Black Sabbath
Judas Priest
Deep Purple
Yngwie Malmsteen
Metallica (3 times)
Pantera
Ozzy Osbourne
Alice Cooper
Scorpions
