Robert Cataliotti presents the background on drumming and rhythm in New Orleans leading up to the invention of the drum set. The presentation examines three of the pioneers of the drum set, Dodds, Singleton, and Barbarin—all of whom played with Armstrong—and discuss their innovations, their impact on the evolution of jazz, and highlight their experiences with Armstrong. It concludes with an overview of how their legacy continues to the present day. The presentation is based on the Drumsville! Evolution of the New Orleans Beat exhibit at the New Orleans Jazz Museum at the Old U.S. Mint (co-curated by Cataliotti) and the accompanying LSU Press book (written by Cataliotti).
