Biohazard SignBiohazard, the Hardcore veterans from Brooklyn (New York), USA, originally formed in 1987, were one of the first to combine Hardcore with Hip Hop elements. They’ve released two demos (in 1988 and 1989), nine studio albums and two live albums (1997’s No Holds Barred is one of my favorite live albums of all times). They wrote legendary songs like Punishment, Tales from the Hard Side or Shades of Grey. As the band had to undergo several line-up changes throughout the years I would need a whole paragraph to mention all of them. But thanks to Wikipedia we have this amazing graph:
