Plummer regularly performs lecture recitals based on her extensive research found in her dissertation: How Spirituals Influenced Both Resistance to Nazis and Civil Rights Protests. In lecture recitals, she performs the spirituals alongside teaching the powerful stories of how the spirituals have influenced the marginalized and oppressed. Since 2024 she has presented this performance in collaboration with singers and pianists at the Cincinnati Song Institute located at the University of Cincinnati College-Conservatory of Music, at the University of Louisville, at The International Bonhoeffer Society Annual Dinner (as plenary speaker) in Boston, Massachusetts, and internationally in Cambridge, England. She gave a poster presentation on this same topic at the NATS National Conference in 2024, and performed a lecture recital later that summer at the Bay View Music Festival in Michigan.

She has guest lectured and taught master classes at the University of Kentucky, All Souls Church in London, England, the Center for Creative Arts High School in Chattanooga, Tennessee, and Bellarmine University. In addition to her private voice study, Plummer enjoys teaching vocal pedagogy mentorship classes to teachers in the Louisville area. 

Plummer brings diverse musical experience to her current singing career, specializing in chamber music, recitals, concert work, and oratorios. In the 2022 International Clara Schumann Competition she won second prize in the professional voice category. She annually performs the soprano solos for G. F. Handel’s Messiah. She is the artistic director and founding member of Soli Deo Gloria, a chamber music ensemble which features violin, soprano, and piano. Some of her favorite performances of operatic scenes and roles include: Gilbert and Sullivan’s The Pirates of Penzance (Mabel) with The Louisville Gilbert and Sullivan Society, Handel’s Giulio Cesare (Cleopatra), and Menotti’s The Medium (Monica) in the Killer Women of Opera concert in Chattanooga, Tennessee.

Plummer received a B.M. in voice performance from The University of Cincinnati College-Conservatory of Music where she studied with Patricia Berlin; a M.M. in voice performance and an M.A. in missiology from Southern Seminary; and a D.M.A. in voice performance from the University of Kentucky where she studied with Dr. Everett McCorvey.
