Young twins, Max and Gabriel, climb a mountain to reach a glacier. Although they resemble each other, they are fundamentally different in their characters. For the humanist Gabriel, this is the first hike and he is deeply impressed by the surrounding nature; the size and beauty of the mountains leave a permanent imprint on his soul. In contrast, his brother Max observes the landscape through the eyes of a scientist. When things come to an end, tragedy will have struck as they reach the glacier.
Why Opera 2.0? New territory is tantalizingly available in practically all facets of this production. First, the musicians will have abandoned sheet music in favor of a graphic video score that permits a much more intuitive style of playing, with fluent combinations of music styles, including avant-garde, music, jazz and rock. Second, the leading role is a "virtual" singer on a video screen. Third, musicians perform on specially constructed musical instruments, designed to play in rare tuning systems. The results are unique melodies and newly imagined harmonies. "Cross of the Enganged", following his "The Glacier - Opera 2.0“ is Klinkenberg’s second opera.
The orchestra is comprised of musicians from Germany, USA, the Netherlands, Luxembourg, Slovenia, France, and Belgium. They are brought together specifically because of their viruosic expertise in performing microtonal music.
