The Festival rainy days presents «Heat!»

November will be hot! At least where rainy days, the Philharmonie’s festival of contemporary music, is concerned. Headlining another multi-faceted, open-minded programme, festival curator Catherine Kontz has chosen «Heat» as the theme of this year’s programming, turning up the temperature in all the Philharmonie’s spaces. As always, a deliberate game of associations is a given when curating a diverse programme for the entire family. New Music fans are just as much the target audience as people who have never encountered contemporary sounds: from the concrete heat of summer or the notion of a sauna to the tackling of «hot» topics, and of course anything that refers to energy or energies… And the 2026 edition of rainy days is not confined to the pillared «safe space» of the concert hall, but seeks out dialogue with other institutions – this time, the Théâtre National and the Casino Luxembourg – Forum d’art contemporain, which is celebrating its 30th birthday.

Discover the festival programme and the range of passes from 17.09. onwards.

  • A performer in a white and pink dress stands on stage, gesturing with both hands. Large shadowy hand images are projected behind her. Musical instruments and props are visible on the dark stage.
  • Two people in white martial arts uniforms spar on a blue mat on stage, while a seated group of musicians plays in the background. The screen above reads Sans les armes, Ago-tsuki.
  • A group of young musicians carrying saxophones walk along an indoor curved walkway with tall vertical windows and modern architectural features in the background.
  • Two women sit at a table lined with potatoes; one arranges them, while the other raises a potato and holds up her hand, both wearing black shirts against a plain blue background.
  • Four musicians closely grouped on stage, each playing different instruments including violin, cello, and clarinet, with dark background and dramatic lighting.
  • A person with long, multicolored hair holds up a wooden instrument and a mallet in a softly lit room, with other seated and standing people blurred in the background.
  • A person draped in a sheer, iridescent fabric stands on stage cradling a bundle, with a marimba and projected background behind them. Nearby, a chair, table with a patterned cloth, and small objects are visible.
  • Five men and one woman in black sit at a table on stage with white napkins tucked into their collars, holding utensils and plates, with a mirrored reflection below. Musical instruments, including a Yamaha drum, are in the background
  • A person stands in front of a table with electronic music equipment, adjusting controls. The background is dark with graffiti on the wall, including the word HORROR in large letters.
  • People are seated on the floor and standing along the walls of a spacious, modern building with high ceilings, gathered around audio equipment in the center for a performance or event. The lighting is soft and ambient.
