Collisions - a 45-minute sonic experience for violin, flute, and organ by composer and sound artist Arthur Bumstein.

This piece uses very simple expanding chromatic arrangements that are transformed into melodies using a random number generator. The composer does not choose the melodic sequence of sounds, but leaves it to chance. This material is united by several ideas - elementary heterophony, simple forms of process, random melodies in a narrow chromatic range, a ritualistic/minimalistic approach to sound, limited performative expression and parallel tempi. The middle part of the piece sounds like an ancient Lithuanian multi-voice sutartinės music.
