MCA

On May 4, 2012, Beastie Boys member Adam "MCA" Yauch died.

What happened
In 2009, Yauch was diagnosed with several cancer-causing glands and tumors that delayed the release of their album Hot Sauce Committee: Part Two. He was unable to appear in music videos for the album, and became a vegan at the recommendation of doctors. At the time, he said that the cancer could be treated, but he was wrong.

On May 4, 2012, he died at age 47.
