Helmut Lachenmann, who celebrates his 90th birthday in the music year of 2025, has composed several milestones in contemporary classical music. Sir Simon Rattle and the Bavarian Radio Symphony Orchestra are dedicating themselves to some of these exceptional works. In his tuba concerto Harmonica, Helmut Lachenmann explores the limits of sound - with music that oscillates between eruption and silence, by means of "strictly constructed denial" (Lachenmann) and by deliberately disrupting the familiar, and eludes socially preformed listening expectations. This appeal to the audience's self-awareness remains as relevant as ever. The soloist is Stefan Tischler, principal tuba player of the Bavarian Radio Symphony Orchestra, and the live recording with the BRSO conducted by Sir Simon Rattle was made on March 22, 2025. Klangschatten - mein Saitenspiel by Helmut Lachenmann deals with the "verso" of sound, it's suppressed and "unwelcome" components. The spectrum here ranges from toneless or muffled sounds to differently coloured noise and clear tones. Lachenmann himself described the piece as " an offer of expressive intensity that reflects the bourgeois longing for beauty and seeks to fulfil it, that is, to overcome it." The work was performed by the Bavarian Radio Symphony Orchestra under the baton of Matthias Herrmann on May 23, 2025 in the Herkulessaal of the Munich Residenz. Helmut Lachenmann, born in Stuttgart in 1935, is one of the most renowned German composers of contemporary music. He studied piano, music theory and counterpoint in Stuttgart and composition with Luigi Nono in Venice. The first public performances of his works took place in 1962 at the Venice Biennale and at the Darmstadt Summer Courses for New Music. He taught composition in Hanover (1976-1981) and in Stuttgart (1981-1999), and has given numerous master classes in Germany and abroad. His works are performed by internationally renowned players and orchestras all over the world. Helmut Lachenmann has received numerous awards, including the German Music Authors' Prize of GEMA (2015) for his lifetime achievements and, most recently, for his compositional work, the 'President of the French Republic Prize' from the Academie Charles Cros (2025).

Ex Nihilo brings together a diverse palette of music into one continuous flow. Ligeti's Musica Ricercata forms the spine of the programme, interwoven with 20th-century works that resonate with it and new interludes by Brecht Valckenaers. Together, they trace a lineage of invention-exploring how composers reimagine their musical language and the piano itself ex nihilo, "from nothing."
