Joana Guerra

ondas batem-me no peito
Impressionist essays inspired by the liquid state, the pulsations and geometries of ocean waves. Sonic fluctuations based on cello, voice, text, wind and electronics.


Joana Guerra is a Portuguese composer, cellist and singer whose restlessness and passion for experimentation has led her to collaborate regularly with numerous musicians from different genres, as well as dance, performance and theater projects, influencing and interweaving a unique universe that is constantly expanding.
She has released four albums of her solo work of the same name, the most recent being “Chão Vermelho”, released in 2020. She is also part of various projects in the exploratory and improvised music spectrum (The Alvaret Ensemble, Lantana), as well as other collaborations with Joelle Léandre, Surma, João Pais Filipe, Gume, Victor Herrero, Ricardo Jacinto, Lula Pena, Yaw Tembe, Asimov, Tiago Sousa and Pop Dell’Arte.

Zé Cruz

Zé Cruz is a multi-instrumentalist musician, composer and also a collector of musical instruments. As well as collecting them, he is interested in understanding how they work, contextualizing their emergence, development and potential mutations; above all, in studying them.

During his residency at OSSO, he proposed recording his first album in his own name, in order to give life and voice to all these instruments that have long been asking to be recorded, crossing sounds, textures and unlikely cultures, accompanied by musicians Sebastião Bergmann, Tiago Martins, Ricardo Jacinto, Luís Sanches and sound technicians Miguel Simões and Hugo Valverde.

Natura Mimesis
Gustavo Costa is a central figure in the Portuguese experimental scene, having been active as a musician, composer and promoter for the last three decades in various musical configurations, and is also recognized as the mentor of the Porto collective Sonoscopia. After his first solo percussion album, Entropies and Mimetic Patterns, released in 2020, in Natura Mimesis the original composition techniques, mostly based on musical transcriptions of natural phenomena, are now applied to a broader orchestral spectrum, with the inclusion of three guest musicians whose backgrounds range from contemporary music to free improvisation. Clara Saleiro on flute and João Dias on percussion have been regular collaborators on various projects, and violinist Biliana Voutchkova is widely known for her involvement in the European experimental music scene.
Natura Mimesis was built around short motifs developed in recording sessions with these three guest musicians, and later composed by Gustavo Costa in his studio, with slight arrangements of the original material, audio processing and electronic counterpoint. As with many of Costa’s compositions, Natura Mimesis is an introspective reflection on the world, where sound is the trigger for an abstract and individual interpretation.


Born in Porto in 1976, his career has been characterized by a constant permeability to various musical styles, but with a common denominator: experimentation and a constant desire for stylistic renewal. Active in the underground scene since the early 1990s, he has maintained a parallel interest and activity in academia, studying percussion, music technologies, sonology, theory, composition and digital media, and teaching at various higher education institutions in Portugal. Over a period of 30 years, he has been part of countless bands and formations of various stylistic spectra, collaborating with hundreds of musicians in countless shows all over the globe. In recent years he has concentrated much of his activity on Sonoscopia, the collective and association of which he is the founder and where he dedicates himself to sonic exploration through various creative and collaborative formats.

MOVE | 21h00

MOVE has an urgency for movement. Where change is not only inevitable, it is intensely desired. Desired in order to exist. From a sense of interconnectivity springs a direct, decisive and ready improvisation. Relentless like the rainforest, fertile like the alluvial fan, blossoming ideas from doubt.
MOVE is the concept and music of bassist Felipe Zenícola (Chinese Cookie Poets, New Brazilian Funk), saxophonist Yedo Gibson (Eke, Naked Wolf) and drummer João Valinho (Rodrigo Amado Refraction Quartet, Fashion Eternal).
The three musicians connect through an unwavering awareness of each other’s creation, where activity and adaptability are sought, where communication and respect are paramount – where anything is possible and the impossible is desired.
Their debut album, The City, was released in April 2023 on Clean Feed Records and their second album will be released in the middle of 2024.
