The Athens Festival’s tribute to acclaimed choreographer William Forsythe will end with one of Forsythe’s more recent works, the performance-installation «Heterotopia,» performed by the Forsythe Company at the Pireos 260 venue tonight to Saturday. If one assumes that dance has always held a defining role in the arts, then that concept was given new meaning by Forsythe. His Forsythe Company became the tool for exploration. «Heterotopia,» something between a performance and an installation, appeals to more than one of the audience’s senses. Powerful movement and speech, set against an unconventional setting – public venues and museums – are the materials used by the inventive choreographer. It is a study on the nature of interpretation and its failed efforts to provide explanations. The work is divided into two complementary parts. The music is by Thom Willems and the sound mixing is by Dietrich Kruger and Niels Lanz. The costumes were designed by Dorothee Merg. The production features interpreters Yoko Ando, Esther Balfe, Francesca Caroti, Dana Caspersen, Marthe Krummenacher, Roberta Mosca, Nicole Peisi, Yiannis Mandafounis, Fabrice Mazliah, Christopher Roman, Yasutake Shimaji, Ander Zabala, Jone San Martin, Elizabeth Waterhouse, Cyril Baldy, Amancio Gonzalez and David Kern.
