Sad news out of the music world.  Beastie Boys co-founder Adam Yauch has lost his battle with cancer and passed away at age 47.

In 2009, Adam 'MCA' Yauch was diagnosed with cancer.  It was thought that he had beaten it, but it came back not to long ago.  After a long hard battle with the disease, he has lost that battle.  He did not attend the Beastie Boys induction into the Rock n Roll Hall of Fame ceremony last month because he was in the hospital.

His influence on both the rock and rap world is huge.  He helped usher in a new age of hip hop, and remained relevant up until the day he died.  The Beasties just released a new album last year, but his illness didn't allow him to go out to perform.
