Erik Nyström's output includes acousmatic compositions, live computer music, and sound installations. The majority of his works are composed for multichannel formats. Some recurring interests in his practice are spatiotemporal deformations and transformations, the emergence of forms, entropic processes, and visual and physical listening experiences.

He is currently a Leverhulme Research Fellow at BEAST (Birmingham Electroacoustic Sound Theatre), University of Birmingham Department of Music, working on a computer music project entitled Synthesis of Spatial Texture Topology in Composition and Performance. The research develops polymorphic real-time synthesis approaches to spatial texture and structuring processes, proposing an aesthetic and technological alternative to conventional fixed-media composition and diffusion performance in electroacoustic music. The work builds on his PhD research, Topology of Spatial Texture in the Acousmatic Medium (download pdf), undertaken at City University London under the supervision of Denis Smalley.

His music has been published by empreintes DIGITALes.
