The synthesizer trio lange//berweck//lorenz reveals meandering worlds filled with colour: Asmus Tietchens is one of Germany’s best-known artists in the field of abstract music. Alongside the new commissioned work “pseudo topos”, lange//berweck//lorenz presents the “Falter-Lamento” from his very first LP “Nachtstücke”. The piece avoids dissonances, sudden accents and brutality of any kind. The repetitive opening motif floats in a whirl through different sound worlds, settling first on one keynote, then on another.

The works by Andrea Neumann and Korhan Erel are part of the trio’s project “Soundtracking”, which explores a new form of collaboration between composition and performance. Neumann and Erel have each constructed a soundtrack to which Silke Lange, Sebastian Berweck and Martin Lorenz play on the synthesizers with minimal specifications. To a large extent the soundtrack replaces a written score. It prescribes a formal sequence within which the three musicians are able to improvise freely to varying degrees. The performers focus entirely on a listening approach to the composition. For “Signale vom Rand” Andrea Neumann has recorded sounds from the so-called “Innenklavier” that she invented and from no-input mixers. The reverb-free space of the no input mixer and the reverberation of the “Innenklavier” are deliberately juxtaposed and connected. The electronic composition “Losing Track in Four Movements” is a study of the development of an audio tape piece that can function both as an accompaniment for improvising musicians and as a standalone work.

Bernhard Lang's “DW30: Loops für Klaus Schulze” was created for the trio lange//berweck//lorenz in 2015. Lang collaborated with Berweck to devise new notation systems. The piece combines instrumental sounds, vocals and electronics and pays homage to one of Lang’s heroes: Klaus Schulze who is regarded as a pioneer of electronic music, a forefather of techno and inventor of ambient music.
