Two Body Orchestra



"Since each of us was several, there was already quite a crowd."

Two Body Orchestra is a hydrid concert/dance performance, centering around our bodies as multitudes — as networks of organs, impulses, technologies, and fictions — as orchestras in and of themselves.

We blur the distinctions between bodies and technologies to the point where even very subtle movements — breathing, tiny shifts of posture — influence and create the sound space.

Two Body Orchestra is the outcome of Roosna & Flak's ongoing research into connecting sound and movement with the help of sensor technology. In this performance every sound is produced by the performers in real time.

We are balancing on the borders of magic and science, leaving a space for intensity, vulnerability and wonder, inviting the audience to notice and create their own stories.

Update 2022: We have continually changed the piece, and have also performed it in music festivals under the name Between Bone and Silence

" Sound and movement interconnect - and two bodies makes a world of both! This evening our audience had the absolute pleasure of meeting an entire TWO BODY ORCHESTRA - and it was intense! Külli Roosna and Kenneth Flak aka. Roosna & Flak transported us into an experience where the physical and audible join eachother - where every sound is produced by the performers in real time. This performance has so many layers to offer, and reminds us that there still is so much play and wonder in our own physical beings." -
