Before the terrible rap-metal trend of the early 2000s, there were a few true collaborations between real deal rap groups and real deal metal bands. This is one of the best political rap bands of the 80s and 90s --Public Enemy-- and Anthrax, a really good metal band also from the 80s and 90s. This collabo produced an extremely popular song that made the rounds on MTV and elsewhere for years. So, TURN IT UP. This is "Bring the Noise," from 1991.
