Darius "Seiko" Elmore is a New York City–based countertenor, educator, and arts leader whose work bridges performance, voice science, and arts administration. Grounded in research across anatomy, physiology, and vocal pedagogy, he approaches the voice as both an artistic instrument and a means of wellness, identity exploration, and authentic expression. A genre-fluid 21st-century storyteller, his artistry spans opera, early music, musical theatre, gospel, jazz, and contemporary repertoire, including collaborations with living composers that challenge traditional boundaries and expand how audiences engage with vocal music.

Committed to artistic excellence, access, and innovation, Seiko advocates for equitable representation, inclusive programming, and the cultivation of emerging artists. As the founder of a private vocal studio, he works with singers across the United States—including artists performing on Broadway, national tours, and in regional theatre—specializing in contemporary vocal technique, pop/rock belting, countertenor repertoire, range development, and evidence-based vocal pedagogy. His teaching is further informed through ongoing collaboration with otolaryngologists, speech-language pathologists, and voice clinicians, allowing him to integrate pedagogical and scientific perspectives into his work.

Seiko is the Founder and former Artistic & Executive Director of Opera on Tap Rochester, where he established organizational infrastructure, produced innovative performances, launched mentorship and commissioning initiatives, and cultivated partnerships that expanded community engagement and artistic access. His experience also includes leadership in higher education, student engagement, production management, and arts administration, contributing to initiatives that foster belonging, interdisciplinary collaboration, and organizational growth.

Alongside his administrative and educational work, Seiko remains an active performer and clinician, presenting masterclasses, workshops, and residencies at colleges, universities, and community organizations. He has been an Artist-in-Residence and guest clinician at Ithaca College, SUNY (Brockport), and Innovation Square. His presentations explore vocal identity, countertenor technique, healthy vocal production, and career development for today's multifaceted performers. His performance credits include works ranging from Akhnaten to Hansel and Gretel, with appearances alongside Opera on Tap, Eastman's Collegium Musicum, to name a few.

Seiko holds a Master of Music in Vocal Performance from Shenandoah Conservatory and continues to develop a career at the intersection of performance, education, and creative leadership. Based in New York City, he is passionate about creating meaningful artistic experiences that connect communities, empower emerging artists, and reimagine the role of the modern musician as performer, educator, producer, and cultural strategist.
