Franco-Austrian choreographer and director Gisele Vienne is fascinated by puppets and brings a group of nine ventriloquists and their marionettes to the stage in her latest piece, "The Ventriloquists Convention." The play is part of the World Theatre Festival Shizuoka run by Shizuoka Performing Arts Center from April 28 to May 7 at venues in and around the city of Shizuoka.
