This is a book only Questlove could have written: a perceptive and personal reflection on the first half-century of hip-hop.

When hip-hop first emerged in the 1970s, it wasn't expected to become the cultural force it is today. But for a young Black kid growing up in a musical family in Philadelphia, it was everything. He stayed up late to hear the newest songs on the radio. He saved his money to buy vinyl as soon as it landed. He even started to make his own songs. That kid was Questlove.

Now, in this landmark book, Questlove traces the creative and cultural forces that made and shaped hip-hop, highlighting both the forgotten but influential gems and the undeniable chart-topping hits-and weaves it all together with the stories no one else knows. It is at once an intimate, sharply observed story and a sweeping theory of the evolution of the great artistic movement of our time. Questlove approaches it with both the encyclopedic fluency of an obsessive fan and the unique expertise of an innovative participant. Hip-hop is history, and also his history.
