INI Movement Jam Sessions

The first 2026 edition of INI Movement Jam Session returns to Patronaat!
On April 2, INI Movement, in collaboration with OSHI, presents the fourth edition of the jam session at Stage 3 of Patronaat. An open jam session where musicians from Haarlem come together to play, experiment and connect. Expect the best musicians and the newest talents sharing the stage for one night, curated by INI Movement.

This edition is led by Theo Artz, whose reserved presence contrasts with the vibrant and expressive sound he brings to the stage. Through pitched vocals, unusual delays and colorful textures, Theo creates music that feels both dusty and fresh at the same time. His constant drive to experiment pushes him toward new sonic territory in both his productions and live performances.

Line up:
Lead: Theo Artz
Drums: Ilja Metsaars
Bass: Lukas Honing
Gitaar: Parsa Abdolbaghai
Keys: Luuk Huiteng
