Adam Keefe Horovitz (born October 31, 1966), better known as Ad-Rock or King Ad-Rock, is an American musician, guitarist, rapper, producer, and actor. He is best known as a member of the pioneering hip hop group, Beastie Boys.
Horovitz was born in South Orange, New Jersey, the son of Doris Keefe and playwright Israel Horovitz, to a Jewish family. He began his music career with a stint in the punk rock band, The Young and the Useless, who would often perform with Beastie Boys. When Beastie Boys guitarist John Berry quit, Horovitz replaced him in 1982, when he was 16 years old.
After Horovitz joined the band, the Beastie Boys changed their sound, evolving from a hardcore punk band to a more hip-hop oriented group. The band was signed to Def Jam, and released their debut album Licensed to Ill in 1986. The album was a huge commercial success, and spawned six hit singles.
In addition to his work with the Beastie Boys, Horovitz also remixes numerous tracks for other artists under the alias 41 Small Stars.
He is married.
