Adam Horovitz, aka Ad-Rock, recently sat down with GQ to talk about his career as of late. The MC will appear in Noah Baumbach's While We're Young, out March 27, alongside Ben Stiller. Horovitz revealed that his rap trio, the Beastie Boys, is officially over. The news comes as little surprise since the group ceased operations following the death of founding member Adam Yauch in 2012.

"We're done," he said. "Adam Yauch started the band. It's not like a thing where we could continue without him."

The MC went on to talk about missing Yauch on a personal level, calling his partner's absence a "huge hole" before going on a tangent about the inevitability of death.

"You can never prepare yourself for this. I feel like, maybe when you're an old person, you can. I don't know how that comes off, but I feel like, when you're old, you know it's happening. You know what I mean? Your brother or your sister's gonna go. Your best friends are probably already gone. All of this -- you're wrapping it up, so it all makes sense. But when you're, you know, fortysomething, you never really -- you don't expect it to actually happen."

Fans can rest easy knowing that there is still some previously unreleased material that may become available at some point in the future. Horovitz called the outtakes instrumentals and "bad jamming." Hopefully, there are some salvageable tracks to release.

Ad-Rock and Mike D are also working on a memoir, which will include some of the former's colorful anecdotes. He said that Donovan became one of his good friends after the Beastie Boys blew up. One of his best stories involved Axl Rose accusing the Beastie Boys of ripping off Led Zeppelin.
