Mike has worked with and toured with the band since 1998, when he took over from DJ Hurricane. He's the shit - need we say any more?

How old are the Beastie Boys?
Mike D was born November 20, 1965. MCA was born August 5, 1964. Adrock was born October 31, 1966 (yes, Halloween). You do the math.
Where do Mike, Adam and Adam live?
The album To the 5 Boroughs didn't answer this question for you? Ok, then. If you didn't get it; they live in New York City.
Do Beastie Boys have their own studio?
Word up. Oscilloscope Laboratories (with the plywood floor) in Manhattan - built by the master carpenter Mark Edwards. But you know this already, because you've read the timeline.
Why do they call themselves Beastie Boys and does it stand for anything in particular?
The name Beastie Boys was made up in the early 1980's by former band member John Berry. They found the name Beastie Boys appropriate at the time and have stuck with it ever since (obviously). So what the hell does it mean? Well, according to Mike it stands for: Boys Entering Anarchistic State Towards Internal Excellence. And that's official.
How tall are Beastie Boys? Who's the tallest? C'mon!
Yeah, who the hell cares anyway? Quiet! Quit asking this one.
Are all three Beastie Boys Buddhists?
The answer to this is a straight up no. MCA is very much into Buddhism, though. He was first drawn to it in early 1990s when he visited Nepal to do a little snowboarding.
Who is Felicia?
On To the 5 Boroughs, a voice sample from a certain Felicia is used. So, who is Felicia? Felicia is like the den mother of Beastie Boys. She has functioned in many roles in servitude to the mighty three. Handling all of the merchandise related tasks, a lot of the tour promotional materials, dealing with packaging designs etc. All in all Felicia is a fucking awesome friend of Beastie Boys and all of us who work with them. Anyone who knows Felicia gets that familiar message on their voicemail, as heard on Rhyme the Rhyme Well on To the 5 Boroughs. "Hi ____, it's Felicia".
How do you pronounce MCA's last name Yauch?
It's more or less pronounced "Yau-k" / "Yow-k" (yow as in wow). Feel free to check out the pronunciation in several Beastie Boys songs.
