Three separate musical worlds
The clearest way to navigate this catalogue is to treat the three names as three distinct projects rather than variations on one sound.
Riverside is the progressive rock band, with full arrangements, vocals and guitar-led songwriting. Its 2023 album ID.Entity dealt with digital truth, privacy and modern technology. Duda left the band on 23 April 2026 after twenty-five years, citing a creative dead end and an internal atmosphere he was no longer prepared to misrepresent.
Lunatic Soul is the project built on organic instrumentation and cinematic melancholy, returning repeatedly to themes of life, death and spirituality. It is where he has said his focus now goes.
Releases under his own name began as an outlet for material that suited neither of the other two. What started as a home for side projects and one-off songs became a dedicated space for electronic experimentation, and is now the established outlet for synthesiser-led instrumental work.
Releases under his own name
Everything released under the Mariusz Duda name, most recent first, with a guide for each. The catalogue is easier to follow once you notice it runs in three strands at once: the electronic albums, the acoustic Subcutaneous songs, and one collaboration.

The three strands
The electronic albums are the main body of work: instrumental, synthesiser-led and largely performed alone. They run from Lockdown Spaces in 2020 through to AFR AI D in 2023.
The Subcutaneous songs are the opposite: sung, acoustic and concise. Duda has described the most intimate compositions as the ones with calm, subdued vocals over acoustic guitar or piano. Two are on the official Bandcamp page, and both were released in 2020 — interleaved with the bleakest of the electronic records, which is why the catalogue can look contradictory at first glance.
One collaboration, The Old Peace with Steven Wilson, predates all of it and stands apart from both strands.
The Lockdown Trilogy
Between June 2020 and December 2021 came three minimalist electronic albums — Lockdown Spaces, Claustrophobic Universe and Interior Drawings — written in response to the isolation of the pandemic period. They move outward as they go: from the sealed room, to the mind under pressure, to the work that gets someone through it. All three were recorded at Serakos Studio in Warsaw and performed by Duda alone.
AFR AI D is their direct successor. It keeps the minimalist electronic foundation but widens the palette with richer arrangements, guest electric guitar and a broader conceptual scope, turning from personal isolation to the cultural anxiety around artificial intelligence.
Sound and working method
The solo material sits in a tradition running through Vangelis, Jean-Michel Jarre and Tangerine Dream, but with a markedly rhythmic sensibility: percussive and sequenced rather than purely textural. It leans on analogue-style synthesisers, drum machines and programmed sequences, with bass playing a supportive, electronic-adjacent role rather than the lead one it takes in Riverside.
Recording is frequently done at Serakos Studio in Warsaw with engineers Magda and Robert Srzedniccy, a long-running collaboration that also covers co-production and mixing. Artwork for several releases has been created by the German illustrator Hajo Müller.

Frequently asked questions
Is this the official Mariusz Duda website?
No. This is an independent music publication with no affiliation to the artist or his representatives. Official releases and announcements are on his own Bandcamp page and the Kscope artist page.
What is the difference between Riverside, Lunatic Soul and the solo albums?
Riverside is a progressive rock band. Lunatic Soul is built on organic instrumentation and themes of life, death and spirituality. Records under his own name are a separate outlet dedicated mainly to electronic and ambient music.
Where should a new listener start?
For progressive rock with vocals, the Riverside catalogue. For acoustic and atmospheric material, Lunatic Soul. For synthesiser-led instrumental music, the solo albums — and AFR AI D is the most melodic and accessible of those.
What is the Lockdown Trilogy?
Three minimalist electronic albums released between 2020 and 2021 — Lockdown Spaces, Claustrophobic Universe and Interior Drawings — written in response to the isolation of the pandemic period.
