See below for a number of elements related to the opera.
First, this is the full documentary on The Exterminating Angel featuring commentary from composer Thomas Adès. The singing begins around 48:20, but the entire thing is a good introduction to the opera, the composer’s creative process, and the production.
Next, if you like you can watch some of Adès’s past operas to get a better sense of his style and soundworld. This is The Tempest, which ran at the Met two seasons ago, based on Shakespeare’s play. This is a scene from Act II.
Feel free to ask me any questions about this opera, opera in general, or the Met before next Monday. I’m excited to see this with you all!
