Odys(s)ee Of Noises is a project founded by Ralf Hildenbeutel, Steffen Britzke and Matthias Hoffmann in 1991, joined by Sven Väth on the first two releases in 1991. Some tracks have been produced by all members together, some only by one or two of them.
The different spellings (Odysee vs Odyssee) had been introduced by a mistake. Even the members themselves are not sure about which version would be the correct one.
