Mac Miller’s family has issued a new statement condemning the release of a forthcoming book on the rapper called Most Dope: The Extraordinary Life of Mac Miller, written by Paul Cantor. “This book is not authorized or endorsed by Malcolm’s family and has been written by a writer with whom Malcolm did not have a relationship,” the statement reads.

It continues: “Furthermore, the writer had no meaningful access to those that were closest to Malcolm—friends, family, collaborators etc. In fact, the writer of this book was made aware at the outset of the process of writing this book that the family and friends of Malcolm were uncomfortable with him authoring this biography, yet he chose to proceed against our polite insistence that he not do disservice to Malcolm’s legacy through writing a book without legitimate primary sources.”

The statement goes on to criticize Cantor and the publisher, Abrams Press, for setting the release date of Most Dope for January 18, the day before Mac Miller’s birthday. “We have been consistently disappointed by the author and publisher’s decision to pursue this book given their full understanding of our discomfort with the circumstances under which it was authored, but utilizing Malcolm’s birthdate as a marketing tool is exploitative and incredibly disappointing.”

Miller’s family urges “those that wish to support Malcolm and his legacy to abstain from purchasing this new book” and instead support another forthcoming book on the late rapper, The Book of Mac, written by Donna-Claire Chesman, in which the estate was involved. Find the full statement below.
