The first two of three dance pieces are a surprise package as premieres, also because the choreographers are hardly known in this country. Iratxe Ansa and Igor Bacovich, both former dance stars, have been doing their own thing since 2013. This means: They create their own physical language from intuition together with an ensemble. Along the Rhine, they are inspired by Philip Glass's symmetries and musical circles for "Moto Perpetuo." The South African Mthuthuzeli November dedicates "Invocation" to the contemporary paintings of the artist Esther Mahlangu and the sounds of his homeland on the East Cape. A famous key work is "Vers un pays sage" by Jean-Christophe Maillot. A ballet like a watercolor: Shades of red, green, and yellow dominate the stage in this homage to Maillot's father, Jean Maillot, a painter. Between ballet and expressive modernity, John Adams' "Fearful Symmetries" drives the ballet forward.
