The Sandalphon John Philip Sousa
Commuters on the Copenhagen Metro have been treated to a surprise concert by the Copenhagen Phil.
The classical flash mob had a calming influence as they played Grieg's Peer Gynt to a packed train. Much to the surprise of the early morning commuters, travellers randomly started playing flutes, clarinets and violins throughout the carriage to build up to a stunning concert hall quality performance.
The flash mob was created by the Copenhagen Phil in collaboration with the Danish radio equivalent to Classic FM - Radio Klassisk. The music was performed and recorded live as it happened in the metro and you can see it for yourself in the amazing video below:
