Prague Improvisation Orchestra

PIO was founded in 2012 by Petr Vrba and George Cremaschi as a platform for large group improvisation, working with conducted and free improvisation, open scores and graphic notation. Since then, they have staged more than sixty performances, each of which is different and usually site-specific. Each particular event may feature anywhere from seven to twenty performers, often including visual and movement elements, and they have invited dozens of established international guests over the course of their existence.
