Adam Yauch, better known as "MCA" in the pioneering hip-hop group the Beastie Boys, died on May 4, 2012 at the age of 47. Yauch was diagnosed with salivary gland cancer in 2009 and underwent surgery and radiation treatment.

"I miss Adam so much," wrote fellow Beastie Boy Michael 'Mike D' Diamond."He really served as a great example for myself and so many of what determination, faith, focus, and humility coupled with a sense of humor can accomplish. The world is in need of many more like him. We love you Adam."

Yauch formed the Beastie Boys with Diamond as a hardcore punk rock outfit in 1979. Adam 'Ad-Rock' Horovitz joined the group in 1982 and soon the Beasties were a full-fledged hip-hop trio. They released their groundbreaking album 'License to Ill' in 1986 on Def Jam Records, which featured the hits '(You Gotta) Fight For Your Right (To Party),' 'Brass Monkey,' 'No Sleep Till Brooklyn' and 'Paul Revere.'

The Beastie Boys released eight studio albums in total, proving that they were more than just a one-hit wonder novelty act. Their ever-expanding musical ambition garnered respect from their peers and fans alike.

Yauch is survived by his wife, Dechen Wangdu, and his daughter, Tenzin Losel Yauch.
