I have been listening to the last movement of Tom Adès' ballet score Dante which was released on disc this Summer by the LA Philharmonic under Gustavo Dudamel.
It was the third act of a collaboration with the choreographer Wayne McGregor and the artist Tacita Dean. The ballet is showing at the Royal Opera House Covent Garden at the moment.
The other two movements (Hell and Purgatory) are very different. Purgatory for example features several recordings of Syrian cantor singing. And I think that's a first for Adès: I don't think he's ever incorporated recordings into his work.
This last movement, however, is 27 minutes of circling, ever-rising uplift. I've listened to it through in one go several times and am never quite sure if it's sublime or cheesy. I'm going for the former. I'd love to hear your thoughts.
