Sound Immersion 2025

Set and Setting

In our work, we have learned the importance of the participants' inner state (set) and context (setting) to create conditions for long-term meaningful change. Therefore we emphasize preparation, not only at the individual level but also at the group level. Throughout the program, the group becomes an important part of the setting for the individual and creates a sense of security and trust that is central to the transformative potential of the experience. The location of the retreat itself is carefully chosen and perfectly designed for this type of work.

Live musician: Juergen Groezinger [DE]

We regard music as a crucial component of the psychedelic experience, and have developed our own musical narrative to support the process. For this program we have chosen to go one step further, and invited the Berlin-based composer, multi-percussionist and certified sound therapist Juergen Groezinger. Juergen is trained in classical music and has played in several prominent orchestras and ensembles over the years. He regularly plays at the Berlin Philharmonic Hall, but his musical expression goes well beyond the classical. He developed and run a number of contemporary solo projects and collaborations, curates music programs for the KlangHaus festival and the radio show WDR 3 KLASSIK KLUB. Experiences of altered states of consciousness have contributed to Juergen's interest in the healing potential of music, which led to his further training as a sound therapist and sound journeys using gongs, bowls and a range of other instruments for meditative states. Read more about Juergen on his website, or check him out on Instagram.

Juergen will participate throughout the program, co-creating the soundscape during the truffle sessions together with us from Nysnö and the group. Juergen brings a range of instruments and an empathetic approach to the space. Our intention is to support the process by feeling the energy of the group in each moment, identifying and meeting needs and expressions during the journey.
