Seán Graves is an American multi-disciplinary artist, electronic musician, and content creator. He is the founder of Conundrum Studio (est. 2000) and the primary architect behind the electronic music project PostOmnis. Known for his intricate approach to sound design and modular synthesis, Graves has spent over two decades bridging the gap between technical hardware mastery and emotive storytelling.

​

Under the moniker PostOmnis, Graves explores a “rich tapestry of sound” that blends soulful melodic structures with complex synthesis. His work is heavily influenced by the tactile nature of hardware, frequently using Eurorack modular systems and custom-built instruments including his well-documented interpretations of the Buchla Music Easel.

His discography reflects a career-long fascination with thematic world-building, ranging from the Lewis Carroll inspired Jabberwocky Sonata (2020) to the atmospheric depths of Mysticism (2026). Graves often collaborates with vocalists and instrumentalists, such as Evangile, Talios Wing, Melismas, CBW, and Michael Mitchell, to add human texture to his electronic landscapes.
