We just got back from a concert featuring an instrument called the World Harp. A group of artists and technicians travel around the world and have concerts featuring this harp.
Tonight, they had constructed it from the base on the ground, to the bridge at the top of a skyscraper. The harp strings were literally strung to the top of the building. The assist stood on the bridge of the harp and played by rubbing the cables with gloves.
Walking through downtown on our way to the concert was a trip. You could hear the harp music reverberating through the city for blocks away. It was amazing! I wish they played every night.
