The video is from the Houston Ballet's performance of "Forgotten Land'. A description of the performance from the PNB's web site is, "Spellbinding PNB premieres by Jiri Kylian and Crystal Pite join Kylian’s sensual Petite Mort and the raucous Sechs Tänze (Six Dances) in an inspired program of contemporary work. The soulful and kinetic Forgotten Land (PNB premiere) expands the Kylian repertory with scenery inspired by Edvard Munch and a haunting score by Benjamin Britten. Sensational Canadian choreographer Crystal Pite delivers PNB’s first Pite work in the riveting power-house ensemble piece, Emergence. "
