In absolutely devastating news, Adam Yauch, also known as MCA, of the legendary group Beastie Boys, passed away from cancer at the age of 47 on May 4.

It was in 2009 when Yauch announced that he had begun treatment for cancer of his parotid gland and one lymph node. The rapper went through surgery and radiation therapy to battle his ailment, delaying the release of 'Hot Sauce Committee' and the group's tour.

The news of Yauch's death came only weeks after the Beastie Boys were inducted into the Rock and Roll Hall of Fame. Such rockers as Slash, Linkin Park, Papa Roach, Disturbed's David Draiman, Limp Bizkit's Fred Durst, Lamb of God's Randy Blythe, Motley Crue's Tommy Lee and more offered their condolences on the very day Yauch passed.

An in-depth eulogy for Yauch was posted on the official website of the Beastie Boys:

"Born in Brooklyn, New York, Yauch taught himself to play bass in high school, forming a band for his 17th birthday party that would later become known the world over as Beastie Boys ... Yauch is survived by his wife Dechen and his daughter Tenzin Losel, as well as his parents Frances and Noel Yauch."
