Folding the paper of reality: Sara Oswald and Feldermelder present a live album that reveals hidden timbres by the means of accoustic and electronic improvisation and signal processing.

Sara Oswald's cello, Feldermelder's electronics and a set of signal paths and fractal algorithms serve as the corner points of their delta-like setup. As a result, their music is a mixture of improvised figures that are processed and extrapolated, before feeding them back into the mix. The musicians shape, echo and (de-)harmonize their fragments, creating a dense and ubiquitous music. Both raw and rich in detail at the same time, Sara Oswald and Feldermelder's play unveils hidden sounds as if they were broken through prisms, creating an ever-evolving, shapeshifting musical journey.

Trained in baroque cello and advocating improvised music, Sara Oswald is the perfect match for sound artist and electronic musician Feldermelder. She plays solo, composes for film and theatre and collaborates with musicians like The Young Gods, Pascal Auberson, Sophie Hunger and Julian Sartorius.Feldermelder's influences range from the works of old pioneers of Electronic Music to classical Jazz, electronic and analog music from the now, before and tomorrow.

Sara Oswald & Feldermelder's debut album "Hidden in Kaoris Castle" was commissioned by the Cantonal University Library of Fribourg; and recorded live at Belluard Festival in Fribourg, Switzerland.
