At times, it's difficult to believe that Mac Miller is only 21 years old. Recently notching up his first Stateside number one album, the rapper has released a total of 8 mixtapes and counting. Now he's ready to take his next step with new album 'Watching Movies With The Sound Off'. Single 'S.D.S.' features beats from Flying Lotus, and is a left field return from an MC who enjoys overturning expectations. Pharrell Williams and Diplo also supply production on the new album, while Odd Future's Tyler, The Creator, Action Bronson and more were on hand in the studio.
