Feygelson's creative practice embraces improvisation and collaboration, blending minimalist, folk-influenced styles with expressive contemporary techniques. He co-founded the i = u Improvisation Festival, a multidisciplinary event uniting music, theatre, dance, and visual arts, based between London and New York, and participates regularly in Finding Rhythms, a socially engaged music initiative supporting songwriting projects in UK prisons and secure mental health settings.
Academically, he holds a PhD from King’s College London, specializing in musical interaction and nonverbal communication within improvisation. He teaches creative music practice and performance at Trinity Laban Conservatoire and is a visiting researcher at the University of Cambridge’s Centre for Music and Science. His research explores cognitive and social dimensions of musical collaboration, focusing on gesture, timing, and group dynamics.
Feygelson is also co-author of an Oxford University Press publication with Milton Mermikides on music and shape in improvisation, reflecting his commitment to blending scholarship and practice.
In May 2025, he collaborated with movement researcher Emma Fisher on their project Water Monitor, exploring the intersection of sound and movement. This collaboration was featured in a performance that highlighted the dynamic relationship between auditory and physical expression.
In June 2025, he participated in the Re:Sound residency at Emerge Lakefront in Sköndal, Sweden. This immersive event brought together musicians, builders, and sound explorers to repurpose instruments and materials, culminating in a unique concert experience that redefined the future of resonance.
Feygelson has also regularly participated in the Resonances series at the Centre Culturel in Paris, performing alongside pianist Kenzo Zurzolo. This series focused on the exploration of sound and resonance, providing a platform for innovative musical expressions and collaborations, with respect to Pauline Olivieros’ Deep Listening and Quantum Listening practices.
In October 2025, Feygelson launched Echos with eco-lobbyist Jordan Allouche, in Paris, an event focusing on shedding light on the environmental legislation being discussed in Brussels, Paris and Washington, D.C. The event will feature resonant harmonic music that will allow community to listen and embody the soul of the legal word, something we rarely have time to directly engage in unless it is our professional engagement. Echos will also extend to other sociocultural causes, such as AI ethics and human rights.
