Watch The Beastie Boys’ “No Sleep Till Brooklyn” And Talk It Out In Our Comments Section

In news fit to ruin your day/week/life, The Beastie Boys’ MCA (Adam Yauch) who had struggled with cancer in his parotid gland and lymph nodes since 2009, was found dead today at 47 years old.

It is currently unclear if Yauch, who cofounded the New York City hip hop group The Beastie Boys in 1979 with Mike D (Michael Diamond) and Adrock (Adam Horovitz), died of complications with his cancer. He leaves behind a wife and a daughter.

The band hadn’t performed live since MCA announced his battle with cancer in 2009, (even cancelling a tour and shows at Lollapalooza and All Points West that year) but it was always the hope that they’d one day do so again.

What a huge, sh-tty bummer.

Let’s all have a nice Beastie Boys lovefest. Leave your awesome MCA memories in the comments. We need some cheering up right now. This is the worst.
