Treehouse NDSM is excited to announce the open call for the upcoming exhibition Two Suns at Once. The exhibition opens on Thursday, 21 May and will close on Sunday, 14 June 2026.
For this exhibition, Treehouse NDSM is looking for projects where two artistic disciplines meet: the visual and the auditory. We invite duo and group applications for an exhibition dedicated to the fertile meeting ground between visual art and music, encouraging artists to collaboratively develop new work or present existing collaborative projects that complement and amplify one another.
At the heart of this exhibition lies the idea of connection and linkage through art. At the same time, the open call poses inherent questions about authorship: what emerges when two distinct languages, sound and visual art, converge? Can Two Suns shine at once or does it become a hybrid? Can artists maintain a recognisable individual voice within collaboration and is that even necessary? Or has the emphasis on individual authorship become outdated and should we look more at collective art practices like CATPC and Ruangrupa do?
Certainly, collaboration brings new perspectives and often leads to unexpected outcomes. With this exhibition, we aim to show that artists today are not bound and limited to a single medium or to the forms they already master when working together. By cultivating and fostering artistic friendship, we believe that works can be pushed further and take on new dimensions. Therefore we do like to facilitate experimenting across a range of diverse media, bringing together musicians, sound artists, performance and visual artists. The selected projects aim to highlight the affinities between image and sound: between the material and the immaterial, the static and the ephemeral.
We invite:
Submission deadline: 29 March
Exhibition Dates: 21 May - 14 June 2026

Selection and Participation
The selection committee, artist Vico Persson, the director and the artistic coordinator will select up to eight tangible artworks to be presented in the space. However, this should not limit your proposal, as we are always open to incorporating temporary or performative works when they meaningfully complement the exhibition. With this exhibition, we foreground connection and partnership with shared works as an outcome. Together, these disciplines can create experiences that are immersive, challenging and resonant, expanding also the perception of the audience.
Structure:
This exhibition will present 8 projects, each pairing a visual artist with a musician. The selected works research how disciplines remain distinct while also generating new forms.
