Adam 'MCA' Yauch the founding member of the Beastie Boys passed away. In 2009 MCA was found to have a cancerous tumor in his salivary gland, and today (May 4th 2012) MCA lost his 3 year battle with cancer. He was only 47. Back in the 80's Beastie Boys helped bring rap into the mainstream music world with their huge debut album ‘Licensed to Ill.’ Just a few weeks ago Beastie Boys were indited into the Rock n' Roll hall of fame. MCA will definitely be missed.
