Cologne, Germany · recorders, piano, violin, voices and electronics

HCK/STR/ZBL is the trio of Teresa Hackel on recorders and voice, Stefan Strasser on piano and synthesiser, and Mia Zabelka on violin, voice and electronics.

The trio's Creative Sources album Köln 60 documents their first in-person encounter, recorded live at BLOCK7 in Cologne on 28 November 2025. The meeting took place on the occasion of Strasser's sixtieth birthday.

The group explores the changing relationships between acoustic instruments, voices and electronics through improvised interaction. Album and artist photographs are credited to Bernd Wendt.
