Yauch passed away of cancer in 2012, leading surviving members Horovitz and Michael 'Mike D' Diamond to put the outfit on a hiatus that appears to be permanent.

Since then, they've been working on a book about their career, although it's at least two years away from publication. Horovitz tells Rolling Stone: "It's like, 'What do you do with your life when your former life is no more?' I have to figure it out - I don't know if I ever will. I'm used to having other people plan stuff for me. I don't plan anything, so at some point maybe I have to start doing that."
