Filament is a Philadelphia-based period-instrument ensemble founded in 2019 by violinist Evan Few, viol player Elena Kauffman, and keyboardist John Walthausen. The ensemble brings fresh insight and expressive vitality to music of the Renaissance and Baroque, creating engaging programs that illuminate the enduring emotional power of early music. The Broad Street Review praised Filament for its "fervor and delight that make early music seem current, and easy, joyful communication," while the Lancaster News noted the ensemble's "profound understanding." Recent programs have included Bach's Musical Offering, Elizabethan song, the music of eighteenth-century Parisian salons, and seventeenth-century Northern German repertoire.

Alice Teyssier is an Australian-born soprano, flutist, and sound artist acclaimed for her expressive performances and adventurous musicianship. Praised by The New York Times for her "transcendently clarion and clear" voice and by the Los Angeles Times as "an arresting soprano, in all senses," she is dedicated to championing overlooked repertoire while collaborating with many of today's leading composers. Equally at home in Baroque and contemporary music, Alice brings uncommon versatility and curiosity to her work as both singer and flutist. As both a vocalist and instrumentalist, she has appeared as a soloist with ensembles including the San Diego Symphony, International Contemporary Ensemble (ICE), Talea Ensemble, Bach Collegium San Diego, and Bourbon Baroque.

A core member of the International Contemporary Ensemble, Alice has premiered numerous works by leading contemporary composers and has performed at major venues and festivals throughout the United States and internationally. Equally committed to education, she has led residencies and workshops at universities across the country and has developed creative music programs for young people through organizations including Youth Orchestra Los Angeles, the San Francisco Symphony Youth Orchestra, and UpBeat NYC. Since 2017, she has served as Clinical Associate Professor of Performance at New York University.
