"Licht- und Schattensaiten" is a musically, partially much experimental one-man-project by Stefan Johannes (also Jahresringe). Here and there it reaches from ruminant calm music to black metal.

The name "Licht- und Schattensaiten" means "Light- and Shadow sides", the word "sides" is meaning the german word "Seiten", but it is a paronomasia with "Strings" (guitar for example), and so it's written "Saiten".
