The first question with the term contemporary is: “Which date is that?” I would sya that I do not know, because the culture historians do not know how they want to call the past present. I have heard many names for 20th century music: Impressionism, Modernism, Neo-styles, Avant-Gardism, Serialism, Microtonalism, Minimul Music and at a certain time Contemporary Music.
I would say that obviously exact classification is tricky.
In this section you’ll find music by contemporary composers, Leo Brouwer, Annette Kruisbrink and Thomas Peperkamp. All with sound and story, but not all with scores because of copyright restrictions.
