The band Wintergatan ((Martin Molin, Evelina Hagglund, Marcus Sjöberg and David Zandén) was formed in 2011 .
Wintergatans "Marble Machine" can be described as a giant music box with 2 000 small metal balls that spins around and create different sounds. After the video was published on Yotube last spring it became a success.
The video has over 30 million views on Youtube.
Today Wintergatan released the piano version of the song.
