What do you get when you combine a swashbuckling tale inspired by Lord Byron with world-class dancers? The answer is Ivan Liška’s Le Corsaire, which receives its North American premiere courtesy of Boston Ballet. Based on the 1863 Marius Petipa version, the choreography was re-created by Liška with help from documents housed at the Harvard University Library. The story involves a noble pirate who must rescue his true love from the clutches of a wealthy aristocrat who wants her for his harem. Romance, adventure and virtuoso dancing await audiences at the Boston Opera House October 27–November 6.
