Oooh, Janacek's Sinfonietta... got to lead you to another great choreographic interpretation of that work, this time by Jiri Kylian, former artistic director of the Netherlands Dance Theater. His ballet on that score might entice you... it really captures the spirit of Tchekoslovakia (as it then existed) in very abstract pictures, and bears Kylian's stamp, in the form of striking profile sculptures and fluid motion throughout.
That video should also be available from a well-stocked video store; if not, let me know. I believe the overall title of that VHS tape was An Evening with Netherlands Dance Theater.
