This is a sad day indeed! This one hits very close to home, like Kirt Cobain or Layne Staley - MCA and the Beastie Boys had a huge influence over the kind of music I listened to in my youth, shaping my musical tastes into what I now know and love as "great music." MCA lost his 3 year battle with cancer today. Life is precious, do what you love, live your dreams! MCA - you will be missed.
