'5 variations on a long string' is an intense exploration of composer/performer Ellen Fullman's creative process and mind-blowing sound world. Over the past quarter century, Fullman has used her own invention - the 'long string instrument' - to develop and perfect a unique musical language. The sixty-foot-long instrument envelops its audience in dense masses of dynamic sound; Esmonde's short doc is an immersion into her subjective sonic world.
