The works on this recording span Varèse’s entire career, containing his sole surviving early composition, Un grand Sommeil noir, and his last, unfinished work, Nocturnal, brilliantly and seamlessly completed by the composer’s disciple and assistant during the last seventeen years of his life, the composer Chou Wen-Chung. Chiefly, though, the recording features the original version of Amériques, for a massive orchestra of 155 players, recorded immediately following a rare public performance at the Warsaw Philharmonic (only its second since the 1920s) as part of the 2005 Warsaw Autumn Festival.
