unterholz (‘undergrowth’) is an innovative audiovisual performance by German artist, composer and cellist Marcus Kaiser featuring members of the Free Range Orchestra. Based on an immersive projection of a camera moving slowly forwards through jungle undergrowth, the piece overlays audio and video from past performances. This becomes a visual analogy for the exploratory, organic growth of a semi-improvised piece as it is performed repeatedly in different places, with different people and different durations, accumulating meaning and identity with each iteration. Unterholz has been performed 23 times since its premiere in 2006, in Austria, Dusseldorf, Munich, Berlin, Ljubjana, and Tianjin (China) among other places. Discover more.

This performance has been made possible by UCA Surrey galleries and the here.here concert series. This event is part of Being Human Festival, the UK’s national festival of the humanities, taking place 7–16 November 2024. Led by the School of Advanced Study, University of London, with generous support from Research England, in partnership with the Arts and Humanities Research Council and the British Academy.
