Olari Elts/Estonian National Symphony Orchestra - "Erkki-Sven Tuur: Aeris". Aeris is the ninth ECM New Series album to feature the vibrant and highly expressive music of Erkki-Sven Tuur. Olari Elts, a long-time champion of Tuur's compositions, conducts the Estonian National Symphony Orchestra in compelling, intensely focused performances of Phantasma, de Profundis and Tuur's tenth symphony AERIS, a vast drama of shifting energies and interactions, which is scored for horn quartet and orchestra. The symphony is in four movements that transition seamlessly. Tuur: "Each movement expresses a different development between the ensemble of soloists and the orchestra. Sometimes their motifs spread into the orchestra like memes that start changing and gradually take on lives of their own..." The album was recorded at Tallinn's Estonian Concert Hall.
