Notice:
Due to technical and organizational reasons related to the artist, the “Cosmotonic Experience” concert-performance by Bern-based multi-instrumentalist and composer Don Li, originally scheduled for September 20, 2026, has been postponed. LAC and Jazz in Bess intend to reschedule the event, if possible during the 2026–27 season, on a date to be determined. 

With the Cosmotonic Experience project, the LAC plaza is transformed into a space open to the public. At its center stands Sphera, an inflatable structure designed by Don Li that hosts a performance lasting approximately six hours, freely accessible and experienced in various ways: while standing still or moving around, entering and exiting the space at any time. 
An internationally active clarinetist, saxophonist, and multi-instrumentalist, Don Li was, in the second half of the 1990s, one of the pioneers—along with the Tonus collective — of a distinctive experimental movement within the Swiss music scene, in which improvisation and other jazz elements intertwined with minimalism, funk, and certain hypnotic and ritualistic music. Over the years, he has developed a personal artistic vision in which the influences of his many interests—ranging from metaphysics to ancient Eastern disciplines, all the way to spiritualism and the various forms of minimalism—giving rise to projects that transcend the conventional format and ritual of the concert to explore expanded forms and ever-changing soundscapes. 
Within the installation, an ensemble of eight musicians creates a musical flow that evolves over time, without a linear structure, inviting a personal and non-hierarchical listening experience.  
At the heart of Don Li’s work lies the idea of music as an open experience, capable of questioning and transcending boundaries. Sound thus becomes a space to be inhabited rather than merely observed—an environment in which the listening experience is freely constructed and continually renewed over time.
