Here´s a photo from the historic square in Antwerp, Belgium.
I was there a few weeks ago. There was a lovely display of folk dance in traditional costumes, some of it involving intricate patterns with swords. While the adult dancers were accompanied by a group of several musicians including pipes and accordions, the music for the children´s dances was played by one fiddler and one recorder player. The surprising thing is that the music was loud enough for all to hear, both dancers and audience, without amplification.
Far from the bustle of the shops, and safely away from traffic noise we were able to enjoy music and dance as they have been enjoyed for centuries: in the open air and with live performances unspoilt by amplification at excessive volume levels.
