Kairos, choreographer Wayne McGregor’s second Ailey Company premiere, fills the stage with sinuous, angular movement and synchronicity. Drawn from the ancient Greek language, the word “Kairos” has dual meanings, the first being the most opportune time to take action and the second being weather. The ballet is framed by Idris Khan’s dramatic set design and played out to Vivaldi’s The Four Seasons, re-imagined by experimental composer Max Richter. Ailey is the first American company to perform Kairos, which originally premiered in 2014 as part of the STEPS contemporary dance festival in Switzerland. Following the Ailey restaging of Chroma in 2013, the 2016 celebration of the 10th anniversary of Wayne McGregor as resident choreographer for The Royal Ballet featured members of both companies performing together in his acclaimed work for the first time.
