Mike D and Ad-Rock have reportedly signed a deal to release their memoirs in 2015.

The book comes following the two remaining members of the Beastie Boys signing a deal with Random House imprint, Spiegel & Grau. The New York Times reports that the book is currently untitled and that it is unlikely to follow the structure of a traditional biography, focusing instead on a “pastiche of voices, images, irreverent humor and pop-culture reference points”.

Julie Grau of Spiegel and Grau offered some insight into what fans can expect from the book upon its release, suggesting it may take a similar tone and form to the group’s 1990 magazine Grand Royale. The Beastie Boys are “interested in challenging the form and making the book a multidimensional experience,” Grau said in an interview. “There is a kaleidoscopic frame of reference, and it asks a reader to keep up.” The book will be edited by Sacha Jenkins, a hip-hop journalist, and will be loosely structured as an oral history of the group from their beginnings in the music industry to the death of Adam Yauch in 2012.
