Conferences are formal. And actually everyone expects them to be so. And the more surprise it is when suddenly among the tired and official audience somebody starts playing the violin. And then there appeared a flute in the hands of another guest. And one more violin supports, and a guitarist adds music and a cello adds.
The five brightest musicians were responsible for this wonderful Flashmob and the surprise was really great!
The impression and the beauty of the music really splashed the day!
