The perfect music to drive mom crazy? The only soundtrack for a frat party? The white rappers to erupt from Brooklyn? This could only be the Beastie Boys. Like milk without Oreos or Shirley without Laverne, rap music without the Beastie Boys would be dull and lifeless. Emerging in the 1980s as part friendly-hip-hop and part in-your-face rap, the Beastie Boys have evolved from "tape-traded" to mainstream by breaking all the rules. Using their music to rap about everything from politics to panties, the trio has paved the way for many followers, all the while urging the masses to fight for the right to party.
