As a ballerina in NYC during the 60s, Marta C. González undoubtably performed Tchaikovsky's Swan Lake hundreds or even thousands of times. González passed away recently — perhaps from complications due to her Alzheimer's, which can affect a person's memory and movements in profound ways — but she had one last chance to revisit her ballet days before she died. In the video above, you can see how, as she starts to listen to Swan Lake in a pair of headphones, she reanimates and begins performing the dance choreography in her wheelchair. Clips from what I'm assuming is her past Swan Lake performance are interspersed throughout the video. What a lovely moment.
