The Ririe-Woodbury Dance Company continued its countdown to the departure of Artistic Director Charlotte-Boye-Christensen, by presenting Three, which took the form of a retrospect of Boye-Christensen’s work, featuring pieces dating back as far as 1995 or as recently as earlier this season.  The show gave a broad overview of the choreographer’s work, displaying not only her exploration of technologies and media, but also an unusually broad expressive range.
