Ryan’s research examines the intersections of classical and popular music in America and the historical narratives that emerge from such points of collision. His first book, “Arranging Gershwin: Rhapsody in Blue and the Creation of an American Icon” (Oxford University Press, 2014), focuses on the ongoing — and surprising — life of Gershwin’s iconic “Rhapsody in Blue” over the course of the 90 years since its inception. He currently sits on the editorial board of the “George Gershwin Critical Edition” and will be editing four separate arrangements of “Rhapsody in Blue.” Ryan is also one of the co-hosts of “Critical Karaoke,” a monthly radio program about music and the ideas it inspires as well as a contributor to the “A Day in the Life” series — both aired on KRCC and streaming online at criticalkaraoke.com.
