Rosie O’Brien

Rosie O’Brien is a musician and organizer originally from Lawrence, KS. She studied Political Science, Studio Art, and Mandarin Chinese at Grinnell College in Iowa and pursued a career in political and environmental activism before transitioning into music full-time. During her undergraduate studies, Rosie sang and toured annually with the Grinnell Singers, where she debuted and recorded the original compositions of her mentor and director, Dr. John Rommereim, in both Iowa and Taiwan.

Rosie returned to Kansas in 2017, where she studied traditional djembe and dunun with Prof. Dylan Bassett via the KU West African Drumming Ensemble; she also joined Lawrence’s annual Mardi Gras parade community as a trombonist, simultaneously founding her own Mardi Gras-style street parade brass ensemble, Sass-a-Brass. Rosie moved to Kansas City in 2021 to expand the project, which has received grants from both the Charlotte Street Foundation and ArtsKC to increase accessibility within community brass bands for women and queer musicians.

Rosie joined the KC Ballet School as an accompanist in 2023 and plays traditional djembe for modern dance classes and the ROAD program. In 2025, Rosie will enter her second season as a soprano with professional choral ensemble Te Deum; she is in her third season as a Choral Associate with Country Club Christian Church, and enjoys performing locally as a vocalist and percussionist with her 8-piece free-improvisation band Apricot Glow.
