Although her repertoire spans many centuries, the soprano Phyllis Bryn-Julson is best known for her performances and recordings of the twentieth-century repertoire, including the works of Schoenberg, Webern, Berg, Bernstein, Carter, Wuorinen, Messiaen, Stravinsky, and Britten. She has collaborated with Pierre Boulez and the Ensemble Intercontemporaine, and her extensive recordings of classic literature have helped to define contemporary vocal performance practice. Bryn-Julson recalls her rural childhood in the American midwest and rise to prominence on the international new music scene; her collaborations with conductors including Gunther Schuller and Erich Leinsdorf; and relationships with the singers Helen Boatwright and Jan DeGaetani, her mentors. Issues discussed include new music interpretation and pedagogy, including aspects of repertoire selection and the maintenance of vocal technique.
