Artist portrait

I’m Dimitris Barnias, a sound artist based between Athens and Crete, making music under the alias tOkeno. My artistic practice explores the intersections of experimental electronics, electroacoustic music, soundscape and algorithmic composition, constructing sonic architectures that challenge conventional listening. Drawing from the raw, meditative textures of Crete’s natural soundscapes and the tense, fragmented pulse of urban Athens, my music unfolds as a universe of its own.

Active in Greece’s contemporary music scene since 2000, I create live performances, sound installations and collaborative works with dancers, visual artists and theatre makers. My approach balances sound programming and free improvisation, often evolving through studio exploration or live interaction. I am a member of HELMA (Hellenic Electroacoustic Music Composers Association) and a PhD candidate at HMU, with works presented at festivals and venues across Greece and internationally.

This website is a growing archive of my sound related work - performances, compositions, research, apps, patches and tools. From time to time, I also share some free goddies like music, patches, apps and personal notes. Subscribe to the newsletter for updates, upcoming performances and exclusive downloads:
