Described as “a radiant new voice in the choral world,” Aeternum has quickly established itself as a leading professional vocal ensemble in the Bay Area. Co-founded by Executive Director Brady Egbert and Artistic Director Bailey Cooke, Aeternum presents innovative programming, powerful performances, and unwavering commitment to the transformative power of ensemble singing. Performing a wide-ranging repertoire that spans centuries, Aeternum brings fresh interpretations to both beloved choral masterworks and underrepresented composers. With a core mission to uplift, inspire, and engage audiences, the ensemble has already gained a reputation for its artistic excellence and deeply moving performances.
Recent and upcoming projects include In Rest and Remembrance, a program exploring themes of solace and rest through works by Gustav Holst, Caroline Shaw, Ralph Vaughan Williams, and others. Future performances will continue to highlight both classical choral traditions and contemporary works, reaffirming Aeternum’s dedication to innovation, inclusion, and musical storytelling.
In addition, Aeternum is committed to education and community outreach, working with underfunded youth music programs to provide mentorship and inspiration to the next generation of musicians. With a belief in the healing and unifying power of choral music, the ensemble strives to create an impact far beyond the concert hall.
