This is the second volume of the Musics in the Margin compilation series. Like volume 1 in 2006 (SR 254CD), this new production mixes visual arts with music, focusing on the affinities existing between three visual art fields considered on equal terms: modern art, contemporary art, and outsider art. Decompartmentalization is the key word, and this record offers unique approaches transcending the simple question of the insider/outsider classification. Based in Berlin, Klaus Beyer is mostly known for his unusual performances of Beatles songs, but this musician's talent is larger than that, as he also writes his own songs, makes short films and animated films, and works as an actor. Normand Cournoyer launched his music career around the age of 70. Self-taught, he has since written an incredible number of songs (more than 1,500 in over 75 languages) using a piece of random composition software. Installation artist, performer, illustrator, sculptor, sound collector, and globe-trotter Baudouin Oosterlynck expands listening capabilities by creating prostheses and musical objects to multiply and increase our ears. The Wild Classical Music Ensemble is headed by musician/audio artist/experimentalist Damien Magnette and four artists with learning disabilities. Othin Spake is an improvisatory project between drummer Teun Verbruggen (Flat Earth Society), guitarist Mauro Pawlowski (dEUS) and Rhodes pianist Jozef Dumoulin (Magic Malik). A major representative of the Italian madrigal style of the Renaissance, Gesualdo's position in music history has been largely re-assessed in the 20th century. Once seen as a marginal, unbalanced composer, Gesualdo is hailed by some as a visionary. The first composer, 300 years before Wagner and the post-Romantics, to make significant use of chromatism and dissonance, and a precursor of the Moderns in his use of extreme contrasts and unusual rhythmical breaks. A composer, violinist, and teacher, Baudouin de Jaer created multidisciplinary works adapted to a complete space. A major artist of the 20th century, Adolf Wölfli was committed to the Waldau Mental Asylum, near Bern, in 1899. Wölfli started drawing, writing, and composing music at the age of 35, working all day long on a colossal body of work, comprising 25,000 pages of graphic compositions, collages, literary works, and music scores. Jacques Brodier, artist and researcher, is the inventor of the "Filtre de Réalité" ("Reality Filter"), whose antennae, using the ionosphere's reflection, receives the electromagnetic noise broadcasted by Earth in deep space. This airwave noise consists of radio signals from everywhere, music and voices in multiple languages lost in a sea of cosmic noise, distorted by untraceable causes or the mishaps of dissemination.
