Since nearly one and a half decade MusicActionEnsemble KLANK conceives, composes, improvises, directs and produces concert events, recordings, films, printed materials, workshops, radio works and musical theater – in occupations from solo to quartett, together with numbers of other professional artists or with large to very large groups of musical enthusiasts


Founded in 2008, KLANK brings together the aesthetic histories and musical approaches of the improviser Reinhart Hammerschmidt (also double bass), the multi-instrumentalist and electronic musician Markus Markowski (also guitar), the composer and instrumentalist Christoph Ogiermann (also violin) and the sound performer and everyday drummer Tim Schomacker.


KLANK aesthetics: Permanent testing of ones own instruments - intensive analysis of compositional procedures, aesthetic concepts and playing styles of the 20th and 21st century - Real time exploring the complex and dense logic of free improvised interaction  –  acquisition of non-musical objects and materials as a tool – visualizing the sound production and the potential performances of concert music. 


Since 2008 concerts, performances and projects, inter alia, at the Akademie der Künste in Berlin, for Musik der Jahrhunderte and at ECLAT Festival Neue Musik in Stuttgart, in Musical High School Lucerne, in Munic and Hamburg, at the interpenetration-festival in Graz, the Kunsthaus Wiesbaden, in Cologne, at Music Current Festival in Dublin, at Kunstverein Halle, at Musikhochschule Freiburg, at  Bremen Theatre, in Frankfurt, in Hannover, at cuba in Münster, an der Highschool Düsseldorf, für klangpol – Netzwerk Neue Musik Nordwest in Bruchhausen-Vilsen and in Emsland as well as during the tour KLANK on the bus on behalf of Netzwerk Neue Musik Baden-Württemberg e.V. 


Since 2018 KLANK is playing also as ANKK L. Performances with this post-industrial-band were given e.g. at BREMINALE, at Bremen Theatre and at Schwankhalle.


In September 2013, a CD was produced in cooperation with Radio Bremen and released by the Cologne label auf abwegen

In 2021 the first LP of ANKK L was released.


The installation-performance MACH MAL! (together with Jan van Hasselt) won the 21. Video Art Award Bremen in 2013. 


For the largest music action StadtKLANK the ensemble was invited by the festival zukunftsmusik / Musik der Jahrhunderte / NWS
