This video, via deathstarchris, is a rendition of Silent Night on a circuit-bent Casio MT-520:

Circuit bent Casio MT-520. Added a severe cut-off filter and a minor cut-off filter and a light dependent resistor and one momentary switch to activate it.

Most circuit bent stuff is heavy on the glitch side. This one is not. More mellow, for the season.

Happy Holidays.
