I went to my local theater to see the movie from the Metropolitan Opera called Yannick: An Artist’s Journey, a new documentary from filmmaker Susan Froemke about Yannick Nézet-Séguin, the Met's new music director. It shows his life in music throughout his whole life. His childhood piano teacher is shown. She's very proud.
I liked it very much. They never forgot to show his love for music. They showed a lot of rehearsal scenes, which for me is a joy. They showed him rehearsing Diana Damrau in La Traviata and the whole cast in The Dialogues of the Carmelites. This last was particularly enjoyable. Try to see it.
Addendum. It went by on the screen very quickly, but Yannick conducted as his Met debut the Carmen I loved so much.
