Schlierf (bass) – and instrumentalists were found, and the first single "Omnis Mundi Creatura" was produced. All contributing musicians were and still are deeply embedded in the "classical" music scene. The title piece directly took off in the clubs of the scene and the project launched the debut album "Helium Vola" in 2001. Style Like all succeeding albums, the debut is a concept album. Here, Horn connects the sinking of the Russian nuclear submarine Kursk in 2000 (the album is dedicated to the victims) and the reactions to this tragedy with songs about youth; its love and how older generations deal with the younger. The song structures are still following a rather "classical" pop scheme, which dissolves more and more in the following albums that feature more medieval madrigal-like or hymn-like styles in the pieces. Nevertheless, it already envisions the direction the project is going to take. Samples and electronic experiments are present, however often introduced in a subtle way. In this way they serve the deep thoughts and emotions Horn covers in a rich variety of facets with this project and that Lutzenberger communicates to the audience in as great variability as precision. The project is not meant to merely convey medieval music and memories. Horn rather wants to unravel the general quality of human life connecting thoughts and ideas of medieval poets with contemporary people. The second album Liod followed in 2004 and has a more stringent concept than the debut. It tells the story of a woman who bears an illegitimate child, her fate and the one of the child that seems to die at the beginning but survives due to a spell. Instrumental, electronic experimental samples form the thread through the album replacing the speech samples used in the first album. "Omnis mundi creatura" is prominently cited, and develops in kind of a leitmotiv like the theme of the song about "La fille aux cheveux noirs", a poem by Houellebecq, whose poetry is already featured on the debut. The two subsequent albums Für Euch, die Ihr liebt and Wohin? are both double albums where ensemble pieces are given much more space than before. This development reaches a climax with the last piece on Wohin? in the style of ars subtilior. The samples and electronic experiments are not set apart anymore but fuse with the pieces. One very good example for this is the "Witwenklage" ("The widow's
