I've heard lots of musics thats performed with mechanical gears, such as tesla coil, calculators, marble machinery and so on. All of them are creative, cool and interesting yet most of these creations lacks with harmony and rythm, since they can only made sounds fits in scale but not with timbre. However, this one fits in the atmosphere of the song surprisingly well, and created a amazing experience for me. Therefore, I would like to send my thanks to you. Such a surprise for an internet touring.
