A Building That Plays Music When It Rains

This building is located in Dresden, Germany. It's called Neustadt Kunsth of passage. And when it rains it starts to play music.
This singing wall has tourists braving stormy weather to listen to its music, composed only when skies are grey.
An intricate system of drains and funnels is attached on the outside of a colourful house in Germany and when it rains the entire building becomes an instrument.

The house is located in Neustadt Kunsthofpassage, an area of Dresden part of an arts project called the Courtyard of Elements.
