He's best known as the King Ad-Rock, one-third of the Beastie Boys, but Adam Horovitz is also the son of playwright and screenwriter Israel Horovitz -- and he'll reportedly team up with his dad for an upcoming off-Broadway play.

According to Billboard, the younger Horovitz is scoring his father's latest work, titled 'Gloucester Blue,' which is set to debut on Nov. 16. Broadway World says Adam's providing "original sound" for the play, which is described as "a black comedy about a dramatic homecoming."

Though he isn't well known among the Beasties' target demographic, Israel Horovitz is no stranger to the stage -- he's written more than 70 produced plays and is a two-time Obie Awards winner, as well as a prolific screenwriter whose Hollywood credits include the Ralph Fiennes film 'Sunshine' and Al Pacino's 'Author! Author!'

Ad-Rock's latest project comes at the end of a busy year for the Beastie Boys; the trio released their eighth studio album, 'Hot Sauce Committee Part Two,' in April, going on to win an MTV Video Music Award for the set's lead-off single, 'Make Some Noise.' They're also among the nominees for the next class of Rock and Roll Hall of Fame inductees.
