Ulysses is a German progressive rock band from the early 1990s with an international line-up. They were part of a colourful scene of new bands, labels and magazines that emerged in Germany at that time. Musically, they were less influenced by the German "Krautrock" phenomenon but initially oriented strongly towards the second generation of British progressive rock bands. Hegarty & Halliwell would have classified them as part of third wave of progressive rock bands, who can also be described as a second generation of neo-progressive bands. So one might not wonder that most reviewers heard similarities to Marillion, Galahad and Änglagård in their music which is characterised by a strong emphasis on melodies and the integration of folkloristic elements, abrupt changes of moods and partly complex and ever changing arrangements often moving towards a climax.
