Anna Kaluza, Jan Roder: Anna and Jan first met in 2004 when they started playing together in different combinations as the Kaluza Quartet (with trombonist Christof Thewes and drummer Kay Lübke), trios with pianst Niko Meinhold or with drummer Michael Griener and various others. In 2020 they played their first duo concert on a boat in Berlin (Hosek Contemporary) and decided to continue with their work as duo. The same year they went to Christian Betz’ studio in Friedrichshain to record their music. Achim Kaufmann was born into a musical family in Aachen, Germany, in 1962, and became fascinated by jazz and the possibilities of improvisation as a teenager. He started writing tunes around that time. Later he studied music at the Conservatory in Cologne and also took classes with creative masters such as Dave Holland, Steve Coleman, Muhal Richard Abrams, George Lewis, and Steve Lacy.
