It's a really great time to be a Beastie Boys fan!
The surviving members of the trio, Mike D and Ad-Rock, just dropped a new (VERY comprehensive) book, and they're doing a lot of fun things to help promote it.
The two stopped by The Tonight Show With Jimmy Fallon to talk with Jimmy all about Beastie Boys Book, and all kinds of other topics!
The topics included stories of the band's name, working with Aerosmith, etc. Jimmy also showed his love for the group by showing a video him rapping along with the Beasties back when he was in high school!
