On 10 December 2025, the City Concert Hall of Leiden (Eel Market Hall) hosted a piano evening featuring the outstanding Kazakh composer, pianist, and researcher Rakhat-Bi Abdyssagin. The concert was organized with the support of the Embassy of the Republic of Kazakhstan in the Kingdom of the Netherlands and with the participation of representatives of the Kazakh diaspora, marking an important step in promoting contemporary Kazakh culture in Europe.

Rakhat-Bi Abdyssagin is one of the most remarkable and bold representatives of a new generation of musicians, the author of two “quantum symphonies,” a number of innovative works, and the book Quantum Mechanics and Avant-Garde Music: Shadows of the Void. His artistic vision intertwines music, mathematics, and physics: he explores the connections between quantum mechanics and avant-garde composition, creating works inspired by the principles of the many-worlds interpretation, uncertainty, and quantum interactions. Abdyssagin’s scientific approach harks back to the ancient tradition in which music was considered a branch of mathematics, and musical harmony was understood as rigorously as a mathematical formula.

The concert program spanned three centuries of musical evolution, reinterpreted through the lens of social transformation and the aesthetic searches of different eras. The evening concluded with one of Abdyssagin’s early compositions, dedicated to the themes of peace and humanism–a musical message to humanity conveyed through the image of birds forced into eternal migration as a consequence of human conflict.

The concert became a notable cultural event and preceded Rakhat-Bi Abdyssagin’s participation in the international conference “100 Years of Spin,” dedicated to the centennial of the discovery of spin in quantum mechanics. At the symposium, the composer presented his research on the relationship between avant-garde music and modern physics, continuing a dialogue between art and science that once inspired Einstein, Planck, and Heisenberg.

The Embassy of the Republic of Kazakhstan expresses its gratitude to Leiden University, the City Concert Hall, programme partners, and representatives of the Kazakh diaspora for their support. The concert by Rakhat-Bi Abdyssagin vividly demonstrated how contemporary Kazakh art resonates within the international academic and musical community, shaping the image of Kazakhstan as a country where creativity and science evolve in close interconnection.
