The Amsterdam Sinfonietta under the direction of violinist Candida Thompson and the Netherlands Chamber Choir led by Martina Batič present an innovative program of Baltic and English works recorded live in concert. The program is bookended by two performances of Arvo Pärt’s meditative work Spiegel im Spiegel, the first with cellist Tim Posner, and the original version for violin (Candida Thompson) as the concluding selection, both performed with pianist Hülya Keser. Ralph Vaughan Williams’s Fantasia on a Theme by Thomas Tallis supplies late Romantic lyricism to the program, while Veljo Tormis’s Curse Upon Iron for choir and shaman drum shocks the listener with primal cries. New to the WFMT library on the program: the tone poem Plainscapes by Latvian composer Pēteris Vasks (b. 1946), evoking the vast expanses of the Baltic plains; and the Concerto per voci e strumenti by minimalist Estonian composer Lepo Sumera (1950–2000), bringing the two ensembles together for a tonal, yet disquieting three-movement work which plays with the sounds of words rather than interpreting the words’ meanings.
