Composer Jessie Cox: with music through the planets

Jessie Cox is many things: drummer and composer, Assistant Professor at Harvard University and Swiss citizen with roots in Trinidad and Tobago. In his music and research, he refers to Afrofuturism and travels through earthly and cosmic spaces. His first book will be published in February 2025.

“Space is the Place” is what Sun Ra declared on his 1973 album by the same name. The African-American composer and bandleader not only dreamed of space as an imaginary destination – for him, it was also a metaphor for a new and progressive world in which black people would be better off than on Earth. Jessie Cox takes Sun Ra literally: his piece Enter the Impossible Cosmos leads us through a musical universe. He developed it in 2022 for the Sun Ra Arkestra, which continues to exist more than 30 years after the death of its founder.

Instead of Venus and Saturn, the planets in Cox’s cosmos have names such as KB, RT or LBD-Moon and instead of a rocket, the journey takes place in the virtual world of the “Unity” gaming platform, which also hosts the visual score of the music. Ideally, the audience also sees this world on a screen during the performance, as the musicians move through virtual space and experience various so-called ‘adventures’.

The musical space of planets

Enter the Impossible Cosmos has elements of a role-playing game: the planets have different characteristics – their gravity, their atmosphere (i.e. gaseous), their distance from the sun and the possible forms of life on them (i.e. ‘sound-based life’). This should encourage the musicians to imagine their own sounds, matching the planets they are currently on during their journey in the piece. Musical orientation is provided by certain pitch ranges and timbres that are assigned to the planets. “The planets are metaphors for musical spaces,” explains Jessie Cox. “It’s about creating a space in imagination through sound. Imagining other worlds is central to Afrofuturism – even if it’s just a small, better world that we can create in music.”

The musicians do this by choosing a “character”, i.e. by slipping into a specific role. Each character has different abilities to move around the cosmos and interact with others: “It’s about relationships, about encounters – I like that word with that sci-fi undertone,” says Cox. Finally, the adventures are instructions to move around in the imagined universe, to change position or even planet (i.e. sound world). No two performances of Enter the Impossible Cosmos are the same; each one is a journey into the unknown. It can be undertaken by ensembles of any size and with any cast.

Bending the white space

Jessie Cox’s composition Black/blackness – After Mantra(s) for solo piano is also based on the same principle, the same game world. It was created during an “encounter” with pianist Simone Keller and can be found on her album Hidden Heartache, which is dedicated to marginalised composers of the last 100 years. It is programmed into this piece that the planets change depending on how often you have travelled them. The pianist is equipped with “sense organs” – a special set of methods for playing the piano.

“Black/blackness – After Mantra(s)” was released in 2024 on Simone Keller’s album “Hidden Heartache”

Before the journey through the planets begins, Simone Keller plays a scale at the beginning of Black/blackness – After Mantra(s) – that seems to descend endlessly, then ascends, until suddenly there is a too large interval: the well-tempered space of the white keys, which are always arranged at the same distance from each other, is bent and broken up. For Jessie Cox, this is also a reference to an acoustic phenomenon: “White noise contains all frequencies in equal proportions. As part of sound art, white noise is established today and marks whiteness as a certain, normative condition of existence. But I want to break this up. I like that the concept of noise is ambiguous in German (“Rausch” can be translated with intoxication or frenzy induced by states of mind and/or drugs).” Jessie Cox’s aim is to open up spaces in which the absurd can take place and to use them in order to reflect on our relationship to them, the environment and life in general. “This also means thinking about exploitation, colonialism and anti-blackness – but also, more positively: about blackness, creolisation, utopias and solidarity!”

Jessie Cox’s book “Sounds of Black Switzerland” was published by Duke University Press in February 2025

Jessie Cox’s research and thoughts have now culminated in a book: Sounds of Black Switzerland was published in February 2025 – the first book dedicated to Black music in Switzerland. “The terms ‘Black Switzerland or Afro Swiss’ could hardly be found in any publication during the writing process. I want to open up a discourse, find a language where there isn’t one yet. Music can be a method for this.” Across the genres, from new music to rap and electronic to pop, Cox presents musicians and pieces and uses them to discuss “Black Life” in Switzerland. Last but not least, Jessie Cox wants to inspire new ways of listening – through the book and through his music. There is a vast, as yet unknown space that we can explore with our ears.

Sound art and music by Martina Lussi: It happens very casually

Lucerne born Martina Lussi studied art and through listening she got into producing sound art and music herself. She explores nature and everyday life with microphones and an audio recorder and taking her impressions back to the studio, she condenses her listening experiences into installations, performances and studio albums, as well as field recordings and soundwalks.

At the beginning of our Zoom conversation, Martina Lussi admits that she feels a bit disorganised. She is currently working a lot in an art library, so she is lacking time to listen and engage with sounds, which is a very important aspect to her. “Listening is something that happens very slow. You can’t just quickly listen to something – you have to start from the beginning and absorb it, otherwise you lose the context. Who really has time to listen these days?”

To get in the right mood for our conversation, she has turned her routine route around Lake Lucerne into a soundwalk this morning – in other words, a walk during which you actively listen to your surroundings. She reads out her listening log to me like a shopping list: “Trolleys, conversations, a jogger running past, my jacket, a dog breathing, ship masts, a person imitating a duck…” We both realise that we can imagine the individual sounds, but that such a description lacks one thing: the spatiality and simultaneity of the scenery. “My music thrives on the fact that many different sounds combine and flow into one another. It’s like a stream in which sounds are suddenly very close, only to dissolve into something else again.”

Frogs or wood?
At the end of 2019, Martina Lussi spent a residency in the Brazilian rainforest, where she was able to immerse herself in an unknown soundscape. “Some of the sounds were unsettling because I didn’t recognise them, especially at night. There was a frog for example, that sounded like wood – someone had to explain that to me first.” Her composition Serrinha Do Alambari Soundwalk is based on an audio walk in the village of the same name.

Footsteps of a group of people crunch on uneven ground and set the rhythm, over which one can hear various birds chirping. Gradually, a synthesiser rises like wafts of mist from the soundscape of the rainforest and merges into gentle tropical rain, until at some point the frogs chatter. Martina Lussi is not interested in reproducing the environment as it apparently sounds in reality – she adds artificial sounds and thus creates new sound spaces, such as dreamlike memories. She sometimes does not bother to cut out the wind that blows into the audio recorder. Some field recording purists would consider this a bad recording, but not Martina Lussi.


The composition Serrinha Do Alambari Soundwalk was released on vinyl in 2020 on the label Ōtium, along with a piece by Loïse Bulot.

Coat or birds?
On the contrary: she repeatedly incorporates unwanted background noises into her compositions. In her piece The Listener, these even become the sole material. It consists exclusively of sounds produced by coats. They became the focus of Martina Lussi’s attention while making recordings in nature as part of a research project on bird sounds: “You imagine it to be so idyllic, but early in the morning it’s often so cold that I’m freezing and have to keep moving. As I’m wrapped up in a thick jacket, it just resonates.” She realised that these sounds often sounded like the voices or even the beating of birds’ wings. She took four jackets, improvised with each one for ten minutes and used them to create a four-channel installation and composition.


The piece The Listener is part of the compilation Synthetic Bird Music and was released on tape in 2023 on the label mappa.

Martina Lussi does not consciously sharpen her ears with listening exercises before she goes into the field: “It happens very casually. When I go into the forest, I smell the oils from the trees, I can’t see far, I automatically enter an attentive state that I don’t have to prepare myself for.” As vividly as she talks about the Brazilian rainforest years later, it becomes clear that listening goes beyond the moment. It creates memories that last for a long time and that you can draw on even in more turbulent times.
