Lost Prayers is the first of Estonian composer Erkki-Sven Tüür’s New Series recordings to be devoted entirely to his chamber music. Scaled-back instrumental forces, however, are no indicator of reduced expressive power, and the volatility of Tüür’s “vectorial” concept emerges forcefully from the first seconds of Fata Morgana which is, with Lichttürme, one of two pieces for violin, violoncello and piano. These pieces are performed by the Estonian trio of Harry Traksmann, Leho Karin and Marrit Gerretz-Traksmann, all of whom have played Tüür’s music extensively and appeared on earlier ECM discs, including Crystallisatio and Oxymoron. The German-based Signum Quartett plays Tüür’s Second String Quartet, Lost Prayers, and Signum violinist Florian Donderer also performs Synergie together with cellist Tanya Tetzlaff. Collectively the musicians underline Erkki-Sven Tüür’s view that “one can build up a really rich and wide palette of sounds with only three or four instruments. You don’t necessarily need a full orchestra to operate with a powerful soundscape.” The album was recorded at Bremen’s Sendesaal in April 2019.
