Today the music world mourned an incredible loss as news spread about the tragic passing of Adam "MCA" Yauch. As one of the founding members of the Beastie Boys, Yauch became one of the most legendary icons in hip hop. Tonight, Brooklyn sleeps without one of its best by their side. We hope wherever MCA is, he's still sipping that def ale with all the fly women and continues to rock this party eight days a week. 

Hit the thumbs for iconic photos of MCA and the Beastie Boys. Rest in power Adam!
