Ravel must be turning in his grave!
The whole point of Ravel's Bolero is the gradual crescendo from soft, gentle music to a deafening explosion by the whole orchestra, ending in what is obviously supposed to be an orgasm. It's a well-known musical/sexual joke.
So what did they do in this video? They stopped it right in the middle, when it was starting to get interesting! Turned out to just be an ad for a hotel. They should be ashamed, ruining a great piece of music like that!
