Earlier this month, author Carole Boston Weatherford and illustrator Frank Morrison celebrated the release of their new picture book in verse, Roots of Rap: 16 Bars on the 4 Pillars of Hip-Hop (Little Bee, Jan. 8), a tribute to the history of this art form. We’ve gathered a selection of photo highlights from the launch events, which took place in New York City.
