Namaste to the guy who taught me the word. #RIPMCA



He's still got more suits than Jacoby & Myers. #RIPMCA



No. Sleep. Till the Pearly gates… If they existed #ripmca



If you wear Puma Clydes or adidas Campuses, you can thank the Beasties for that. #RIPMCA



First and best examples that if you understand, appreciate and love Hip Hop, you can be yourself and make a contribution. #RIPMCA



#ripmca So sad to hear that Adam passed away. He will not be forgotten. A legend in hip hop, heart goes out to his family and friends



Yauch had real soul. The day after 9/11 he was the first person I heard talking about compassion. A legend and a loss. #RIPMCA
