projektbeschreibung  (english see below)


"unterholz" ist ein stück das sich (wie reales unterholz eines waldes) im lauf der zeit, d.h. von aufführung zu aufführung und von ort zu ort verändert, material mit sich führt, sedimentiert und dazu neues material ansammelt.

die grundsituation ist die einer installation mit einem zuspielband aus sinus-klängen und einem video einer sich sehr langsam durch ein "urwald-dickicht" bewegenden sequenz.
während der aufführung werden von einigen stellen aus video- und tonaufnahmen gemacht, die dann bei weiteren aufführungen in die video/ton sequenzen eingearbeitet werden.

die aufführung kann konzertant oder sehr lange sein,
dann haben die instrumentalisten  ihren platz und können kommen und gehen.
die orientierung erfolgt nach der uhrzeit und zeitangaben in den stimmen, die eine koordination mit dem zuspielband/video ermöglichen.

UNTERHOLZ (“undergrowth”) is a piece, that, like real undergrowth in a forest, continually changes in the course of time, i.e. from performance to performance and from place to place, carrying and sedimenting old, accruing new matter.

The base situation is an installation with sine tones played back and a video showing a very slow sequence moving through a “jungle thicket”.

Each performance of the piece is filmed and sound recorded. These recordings are then processed into the video/sound sequences for subsequent performances.

Performances may be concert length, but they can also be very long. In this case the musicians have their places and may come and go.

Unterholz is an interdisciplinary work that combines video projection, audio, and live music. The visitors' senses are flooded with accumulation in all layers of the work, in what the artist himself calls a jungle thicket. It is up to the visitor to follow their own path through this environment of sound and image. All the layers in unterholz are the work of Marcus Kaiser: the composition, the audio and visuals, and the editing and processing of the latter. Unterholz is not a work that is simply performed anew each time, but rather a continuous circular process. Each performance of the piece is filmed and sound recorded. These recordings are then processed into the video and sound sequences for subsequent performances. This process is repeated with each performance, embedding each previous version in the next one.

For unterholz Kaiser took inspiration from mycorrhiza. This symbiosis between fungi and plant root hairs, mostly found in jungles, is a nearly lossless cycle of precious nutrients. In the context of unterholz the term, in a broader sense, refers to collaboration between different disciplines: drawing/painting and photography – image and sound – live performance and recording. In unterholz Kaiser also works with foreground and background, similar to the double system of evolution and co-evolution. The development of the interdisciplinary work can only take place in its complete form of visual and sound elements, of recording and live performance. It is impossible to separate the video/audio “background” and the live performance “foreground”.

The first unterholz video originated from Kaisers photography work mykorrhiza I (layering of jungle recordings with photos of this grüne bilder paintings) by applying minimal changes in position and scale, creating a slowly shifting sequence. This video was the “background” for the musicians that played in the first performance. The score was orchestrated for sine tones and played softly in the performance space. The instrumentalists' parts were derived from the score and weaved into the framework of sine tones.

The instrumentalists' parts are a growing part of the whole and originate from the score, depending on the circumstances of a new performance, like new ways and paths in a growing forest. The parts are so called “open scores” in which aspects like timing and played material are free within determined time frames and given material. They are played with a stopwatch, ensuring the correspondence of transitions through the score in all layers of the work. The instrumentation can vary from a soloist to large ensemble, from classical instrument playing and singing, to unpitched objects and spoken words. Thanks to the circular process in unterholz, more and more people appear in the image and sound, merging together and disappearing into the thicket, becoming a virtual ensemble that plays together beyond the boundaries of time.

Since 2006 twenty performances of unterholz have taken place, which are embedded in the Musica Sacra performance. In turn this performance will be a permanent part of the whole of unterholz, appearing in feature performances. The musicians during Musica Sacra are Marcus Kaiser (cello), Antoine Beuger (flute) and Germaine Sijstermans (bass clarinet).

Marcus is a cellist–painter–architect–composer–builder/designer–maker of sound pieces–video artist. He studied cello at the Robert Schumann University of Music and Media in Düsseldorf before graduating from the city’s Art Academy. He is part of the international wandelweiser group of composers and active worldwide as an artist and musician. In 2001 he received the “Förderpreis” of the city of Düsseldorf, where he has his atelier.
Pursuing an interdisciplinary approach, Kaiser produces works oscillating between art and music. Usually working simultaneously on different series and groups of works over long periods of time (years, decades), the artist sometimes combines the results to complex installations on the occasion of major exhibitions – installations that may provide him with a starting point for interactions and further works of art. Nature and ecosystems are recurring themes in his work, be it literally (as in his installations), as a subject (like in his paintings), but also in the rhizomatic manner in which the works in his oeuvre are interconnected.

Antoine Beuger is a composer and flautist. In 1992, he founded Edition Wandelweiser with Burkhard Schlothauer, of which he is artistic director, and in 1994 established the well-known KLANGRAUM concert series in Düsseldorf. Beugers music has been performed and recorded worldwide and has received several international prizes.

Germaine Sijstermans is a clarinetist, composer and installation artist. Since 2020 she is connected to new music production house Intro in Situ (Maastricht) as artistic developer. She is currently working on the development of her works that intertwine composition and installation art, with support of the Performing Arts Fund NL.
