One of William Forsythe's first big creations on becoming director of the Frankfurt Ballet 15 years ago, Artifact is a full-evening work in five movements that helped reveal the way he was heading towards changing the face of ballet. Now it has its first British performances, given by the Dutch National Ballet. Favourably remembered for their contribution to the Van Manen celebrations at last year's Edinburgh Festival, they should do full justice to Forsythe's characteristic mix of movement, music and space. Everything is fragmented and fitted together again in often unexpected ways - even the music, which consists of Bach's Chaconne in D major, freely varied and modified at the piano by Eva Crossman-Hecht.
