RE:duo (“Reply Duo”) engages audiences with innovative programming that blurs the lines between artistic disciplines. Consisting of saxophonist, Wilson Poffenberger, and violist, Elsie Bae Han, the duo formed following an interdisciplinary collaboration exploring the intersection between sound and movement. RE:duo has since expanded its repertory to include works that feature performative elements such as theater, improvisation, movement, and speech. With a principal objective of elevating and connecting with other artists, both duo members founded and hold executive positions with New Music Mosaic, a new music collective dedicated to the promotion of a more equitable musical community through the performance, creation, and dissemination of new music by artists of diverse backgrounds and identities. Through New Music Mosaic, RE:duo curates a series of concerts across the U.S. as a part of their open call for scores initiative. 

Most recently, RE:duo completed their first major Call for Collaborators as the ensemble in residence at New Music Mosaic. Through this call, the duo selected six composers from around the world to compose new works for RE:duo’s debut album as well as their 2025/26 concert season. The composers chosen are: James May, Juwon Lim, Luiz Castelões, Clifton Ingram, Chatori Shimizu, and Frej Wedlund. The composers selected represent the diverse range of new music RE:duo strives to present to their audiences including music that incorporates free improvisation, Brazilian influences, mechanical props, and more. Recognized nationally and internationally, RE:duo has performed at conferences and institutions such as the Composers Conference, the International Saxophone Symposium, the Cortona Sessions for New Music, the North American Saxophone Alliance Biennial Conference, Avaloch Farms Music Institute, Valdosta State University, Georgia State University, the University of North Texas, and the Boston Conservatory at Berklee.
