Swedish band Wintergatan has unveiled a project 14 months in the making, and it is blowing our minds.
The project, simply called the Marble Machine, uses 2,000 metal marbles and 3,000 parts to play a catchy, dreamy tune.
The melody is played by vibraphone, but the instrument also utilizes cymbals and guitar strings, Gizmodo reported. The whole contraption harkens to old musical boxes, or even player-pianos. It all works on the positioning of each marble and the timing of its drop into the right spot. See for yourself:
According to this behind-the-scenes video, the machine was so big and heavy, it couldn’t be moved to a studio. So, Wintergatan simply improvised a studio space where the machine was built.
