Les_Espaces_du_sommeil
Les Espaces du sommeil is a work for baritone and orchestra set to a poem of Robert Desnos[1]: 539–540 [2] by the Polish composer Witold Lutosławski. It is in one movement, with a three-section scheme but lacking clearly marked caesuras, about which Lutosławski stated: "Les Espaces is neither a song nor a set of songs, but a symphonic poem with a baritone solo."[3]
Composed in 1975, it was first performed on 12 April 1978 in Berlin by the baritone Dietrich Fischer-Dieskau and the Berlin Philharmonic Orchestra under the direction of the composer.[4] The piece is Lutosławski's first composition set to the poetry of Robert Desnos, to which the composer returned in 1990's Chantefleurs et Chantefables.[5][6]
