Ottman Gronberg

Ottman Gronberg is a Swedish DJ and producer and the founder of OpenMind. Operating from Stockholm, he has spent the last decade shaping a sound that sits between peak-time power and hypnotic restraint — driving, melodic techno built for the deepest hours of the night.

Since launching OpenMind in 2018, Gronberg has used the label as a platform for an uncompromising vision of underground techno: releasing across its catalogue, building a roster of Stockholm's most uncompromising techno talent, and hosting the weekly OpenMind Radio show that documents the label's evolving sound.

As a performer he is known for long-form, narrative-driven sets that move from brooding ambient openings to relentless climaxes — holding rooms from Berghain to Slakthuset and stages across Europe and Asia.
