Mike D formed the Beastie Boys with Adam Yauch in 1981, soon adding Adam Horovitz to the group. They started out as a punk band, but they found their calling with hip-hop music. In 1985, they opened for Madonna on her famous "Like a Virgin" tour. The Beastie Boys gained huge success with numerous albums and tours, then later founded their own record label and magazine called Grand Royal in 1993. Mike has also worked on musical projects with Mike Watt and Kenny 'Tick' Salcido, as well as Miho Hatori and Yuka Honda of the band Cibo Matto.
