Erkki-Sven Tüür: Le poids des vies don vécues. The main characteristic feature of Tüür’s music is an intense energetic transformative dimension. The intuitive and rational approach is synthesized into a complete organic system. Instrumental music makes up the main body of Tüür’s work. He is the author of eight symphonies, a number of works for symphony and string orchestra, nine instrumental concertos, a wide variety of chamber music and an opera.
