Rhymes in the Flow is the product of great learning and greater passion. By turns playful and provocative, incisive and irreverent, the book excavates some of rap's mysteries: how MCs flow to a beat, how the art of MC-ing has evolved over the years, how rap styles are born. The authors' passion is apparent, as is the impressive range of their research. Smith and Joshi have written a hip-hop book like no other." - Adam Bradley, author of Book of Rhymes: The Poetics of Hip Hop
