Recording of performance 019 of the Polyphony concert series from November 18, 2025, at the BAIZ in Prenzlauer Berg, Berlin.

OUR GUEST FOR THIS EVENT: Holger Tretzack

Holger Tretzack is a guitarist, composer, and producer who blends live instrumentation with intricate loops to create his signature sound. A fixture of the Berlin music scene for over 30 years, he earned cult status primarily as the founder of the live drum and bass band Human Sampler.

ABOUT THE EVENT SERIES

Every third Tuesday of the month, there is a performance at the venue where the both may perform as a duo, or as a trio with different guests, or maybe even solo from time to time. The music explores a wide range of sonic possibilities, starting with the electric guitar and atmospheric electronica and venturing into uncharted soundscapes. They see themselves as influenced by Berlin’s tradition of experimental and informal art and music.

“Polyphonie im BAIZ” pushes the boundaries of genres, creates new sonic spaces, and celebrates spontaneous musical interaction. These performances are open, allowing for freedom of expression and resulting in daring and unpredictable creations. The outcome of each performance is always provisional, leaving room for the unexpected in future showcases.
