Beastie Boy Adam "Ad-Rock" Horovitz has apologized for past misdeeds. Time Out New York recently printed a review of the Beastie Boys' new anthology, "The Sounds of Science," noting that the rap trio has yet to address the homophobic lyrics on its 1986 debut album, "Licensed to Ill."

MTV News reports that Horovitz sent a letter to the magazine acknowledging that the Beasties' attitude toward homosexuals in its early years was offensive. "I would like to take this opportunity to formally apologize to the entire gay and lesbian community for the [expletive] and ignorant things we said on our first record," Horovitz wrote. "There are no excuses. But time has healed our stupidity" . . .

Lance "Un" Rivera, the man New York police believe was stabbed by rapper Jay-Z at a Manhattan nightclub two weeks ago, appears on the credits for Jay-Z's forthcoming album.

SonicNet reports that on the liner notes of an advance copy of the rapper's "Vol. 3 . . . Life and Times of S. Carter," Rivera received a co-production credit for the song "Dope Man," which includes guest vocals from DJ Clue and MTV News anchor Serena Altschul. Rivera, however, is the only producer or fellow rapper who worked on the album whom Jay-Z does not acknowledge in the liner notes' "Thank You" section. Jay-Z's "Vol. 3" will be released Dec. 28 . . .
