AVK4 is the cryptonym of Clemens Kowalski and Oscar Loeser. Together, they seek to investigate the moving image in the space between theater and installation. Their work is aligned with media philosophy and real, live encounters of image and space. Founded in 2013, AVK4 developed an installation, Kapsel, which adapts to any space in which it is shown. AVK4 also provide visuals for (dance) theater companies and mappings. Loopstation was developed in 2017.

GERTJAN BIASINO constantly looks for the synergy between different media. Gertjan studied audiovisual arts (experimental film) at Sing-Lukas Brussels, where he focused on combining film with theater, performance, and fine arts.

While producing his projects, he considers how the audience will access the world he creates in his installation-performances. In addition to his own work, Biasino collaborates with other artists in Belgium and abroad. He specializes in real-time video installations in combination with moving objects and practical effects.
