Afterthought

Improvised Soundscapes with Joachim Weiss and Eckard Koltermann

“I wanted to create music that is like nothing else in the world, so that the listener's imagination is stimulated by the music to enter this completely free subjective space, where he can experience worlds that he would otherwise never experience.” (K.H. Stockhausen)

A lot of time has passed since then. While sine wave generators and tapes were used to produce electronic sounds in the early days, the invention of the synthesizer has led to the development of an unimaginable variety of electronic sounds. These sound generators are no longer only used in serious music. They have also found their way into popular music.

However, Stockhausen's early musical approach of stimulating the listener's subjective imagination remains the central idea of the project “Nach dem Denken”. For the sound journey, a mixture of composed and freely improvised elements will be created.

The performance is intended to offer the listener a space in which to devote themselves entirely to the experience of sound diversity.

The bass clarinettist Eckard Koltermann is one of the pioneers of improvisational music from the Ruhr region, with a European network. Since the 1980s, he has been moving between jazz and new music, theater and chamber music, literary settings and experimental music films. Once a founding member of the Grubenklangorchester, one of the nuclei of the German improv scene, he was a member of the CL-4 clarinet quartet with Theo Jörgensmann, the German Clarinet Duo and Willem van Manen's Contraband, was musical director at the Schlosstheater Moers and maintained various ensembles, one of which was called “Borderhopping”. Whatever Koltermann tackles, he likes to cross borders.

Achim Weiss, a long-time member of the Siegen University Big Band and pianist in various Siegen jazz bands, returns to his early musical roots with the “Nach dem Denken” series. His love of experimental, improvised music is combined here with his enthusiasm for electronic sounds of all kinds.
