"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.

"For many years, Achim Kaufmann has been one of the most inspiring and exciting personalities of the European jazz and improvisation scene. His music bears witness to great harmonic subtlety and structural depth. A brilliant pianist and composer, his reflected exploration of tradition has led him to a nuanced, contemporary sound language that encompasses poetry, energy and abstraction in equal measure." "-Julia Neupert, SWR radio
