Spheres is a piece that lasts about four minutes and somehow came into being while reading the hefty book Sphären by German philosopher Peter Sloterdijk. The hyper-complex, associative language made me reflect. Spheres begins with the sound of fingers brushing over strings, interrupted by short impulses that pop up like bubbles, forming a melody before suddenly bursting. From that moment on, the sphere universe transforms drastically: strings become out of tune, bubbles are distorted and weighted down until they collapse into a messy flamenco of clattering strings. They continue to descend, until a string is completely torn from the guitar.• Premiere: Johannes Westendorp, June 6, 2004, Kasteel De Pinte (BE) • Video: Sjors van der Mark – acoustic guitar, Merijn Bisschops – composition & video
