Free audiovisual improvisation for butterfly, custom-made interface c::ntr::l and electric bass. I C::ntr::l Nature is an action of audiovisual improvisation conceived and live performed by Marco Donnarumma aka The !S.A.D!. The live act represents the celebration of an hypothetical instinct able to govern everything. The performance proposes an univocal, synesthetic action. The aim is to define what Control really represents. The action, the whole body gestures, images and sounds that take life in front of the eyes of spectators create an ephemeral visual-soundscape which can exist only in that time and space. This performance is possible with the custom-made Human Computer Interface C::NTR::L developed in Pure Data by Marco Donnarumma.www.thesaddj.com/icontrolnaturewww.thesaddj.com
