son et lumière : an outdoor nighttime spectacle that combines dramatic lighting effects with recorded sounds and music, usually staged at the site of a famous and historical building, often telling its history.
I was once with someone from the Czech Republic while traveling there who loved the sound of the word tomorrow
He loved it for the sound, however, I think back and I also wonder if he liked it for the sense of possibility and hope in such a dark period of that country's recent history.
