David Byrne. Igor Stravinsky. Gene Kelly. The Mandalorian. William Blake. These are just some of the continuing influences on the choreographer Michael Keegan-Dolan, who brings his acclaimed 2022 work, How to Be a Dancer in Seventy-Two Thousand Easy Lessons, to St. Ann’s Warehouse for its North American premiere. Though he hadn’t performed in any of his works for 20 years, Keegan-Dolan returned to the stage for this one because it’s about his own coming of age. Ballet school, music, Catholicism, IRA violence, and Irishness are woven into a danced journey, or is it a journey into dance. Onstage with Keegan-Dolan is his longtime collaborator, the amazing Rachel Poirier. —Laura Jacobs
