4-Hands Electroacoustic DJ’s

With my friend and colleague Alejandro Montes de Oca, we are exploring 4-hands deejaying, live-mixing our own sonic material.

Confinement Tracks

During the covid-19 outbreak I’m spending days/nights at home exploring directions for a new, synthetic-sounding project. I’m uploading sketches on soundcloud – one track per day!

Aave / Album (2019)

My latest solo album, Elli Records.

Aave is Finnish for ghost, or phantom. The album intertwines compositions from two imaginary times: a series of piano works from an early summer morning in 1952, and a set of electronic pieces from a late October evening in 2022. Piano notes played seventy years ago by unknown hands set in motion electronic processes four years ahead.

As time inflates and becomes bi-fold, personality becomes transparent, objects cease to exist as defined points in space. Sounds dilate into a phantomatic presence.

The music is full of ever-changing textures, and multi-layered. Luminous and spatial in the 1952 piano works, dark and focused in the 2022 electronics. AAVE is non-polished, sketch-like; a sculpture that retains the coarse beauty of its original materials.

AAVE is my solo release, a new affirmation of a highly personal sonic quest. No ready-made electronics here. The album is composed with personal recordings of a 1952 upright piano, custom-coded sound processing modules, field recordings and synthesizer patches.






















Motet :: silent audio installation for 32 loudspeakers (2018)

Motet is a silent audio installation for dancing speakers. The work builds a paradox at the interface of sound and movement: the loudspeakers are driven with infrasound frequencies that are not audible to human ears but manifests itself as a series of hypnotic movements.

R A U M :: Audiovisual Installation (2015)

Raum {m} /ʁaʊ̯m/ space, room, region, roomth [obs.] [room, space], chamber [archaic], area [region, district], territory. Imagination grows from the unknown. Unmapped territories present the possibility for something else to be imagined. At the anthropocene, with all lands conquered, every mountain climbed, every species named and indexed; – where is the horizon of our imagination? R A U M is an installation made of large imaginary maps with vibration speakers attached in them, transforming them into loudspeakers. The piece operates a zoom into sound and the abstract landscapes represented by the maps. The spectator is invited to conquer his/her own space by colonizing the maps with drawings, stickers and other personal interventions. Over the exhibition period, the maps morph from empty to inhabited, owned, colonized.

Riisuttuna :: Dance performance, Satu Tuomisto + Comp & Otso Lähdeoja (2014)

Riisuttuna (Bare) is a wild hybrid of contemporary dance and contemporary music.



Full Contact for Cello & Electronics (2013)

Full Contact is a piece for cello and and an acoustically active space. Sound is driven into the structures, walls, windows and furniture of the concert space, making them vibrate and transform the into sound sources. The space acts as a sonic prolongation of the cello as well as a counterpart of a musical dialog. The music is about contact: contact with the instrument, contact with the sound. It emphasizes physicality, gesture, and maybe sweat; the corporeal dimension of music. W/ Emilie Girard-Charest, Cello.




O V A L :: Audiovisual installation, Otso Lähdeoja & Lenka Novakova  (2013)

(O V A L // Audiovisual Installation // Otso Lähdeoja & Lenka Novakova // Hexagram, Montreal 2013 // 10 large sheets of glass are hanging in a dark room. The glass sheets vibrate and emit sound, forming a spatial polyphony of sonic objects. Video footage of the spectators themselves is pro- jected on the glass sheets, creating a maze of self-portrait reflections and transparencies. The spectator is immersed into a chimerical space of sonic and visual illusions.

Halu :: Contemporary dance performance , Satu Tuomisto + Comp & Otso Lähdeoja (2013)

 HALU is energetic movement, strong music, explicit emotions and lots of wanting. And perhaps some getting.




Chordophones :: Audiovisual installation (2012)

Ten different string instruments hang from the ceiling, each with its own look, feel and history. All the instruments are equipped with transducers driving sound into the soundboard and making the instrument vibrate and emit sound. The chordophones thus come to life with their own voices – a 10-channel audio stream is generated by a custom software. Visitors are invited to move freely in the space, discovering the instruments and their individual voices.
