💥Our album *Residual Light* is the subject of a fine article by Martin Hufner in the Hörbar section of the Neue Musik Zeitung:

„All these musical works are characterised by their uniqueness in the fields of composition, interpretation and improvisation. So much here is conceived in such an airy, unpretentious way, so far removed from personalism and egocentricity – something that is rare to find these days, when personal self-promotion is constantly becoming the central aesthetic element of communication. This is refreshing and should certainly set a precedent.“

🙏🏼Thanks to all the musicians who took part in LAB26 and in the recordings.

💥Ensemble Spotlight!
Over the coming weeks, we’ll be taking you behind the scenes to introduce you to the members of the open music ensemble. We’ll be kicking the series off with our violinist, Felix Borel! 👇

Felix Borel – Violin
Felix is an artist with an impressive stylistic range. Alongside his permanent position with the SWR Symphony Orchestra, he is constantly seeking new artistic inspiration through improvisation. His versatility is also reflected in his work with renowned ensembles such as ensemble recherche, Camerata Bern, Trio Ginko, the Kurmann Strings and the Helios Quartet. He holds a teaching post in improvisation at the Freiburg University of Music. Felix has been a permanent member of open music since 2018 and has significantly enriched our work with his creative energy ever since.

💥Ensemble Spotlight!
Our weekly series on the musicians of the open music ensemble continues; today we are excited to introduce one of the three artistic directors and board members: Roderik Vanderstraeten

Roderik Vanderstraeten – sound director, composer, musician, sound engineer, open music Artistic Director
Roderik Vanderstraeten works as a sound engineer, sound director and recording producer at the intersection of composition, electroacoustic practice and the performing arts. The focus is on music production: sound is developed as a formal and spatial structure, documented and translated into performance or release formats. Depending on the context, this results in sound scores, cue structures, live setups, studio realisations and reproducible workflows.
He studied music theory, piano and classical guitar, trained in dance and the performing arts at the Rudra Béjart School in Lausanne, and subsequently completed a diploma in audio engineering in London. Since 1998, he has worked as a freelance sound engineer, sound director, sound designer, composer and musician for stage and media. Since 2019, he has been a board member of open music e.V. Stuttgart, where he is responsible for production and laboratory formats that bridge composition and improvisation – particularly in recording, documentation and concert formats.
