Commissioned by ACIMC, with the support of Ernst von Siemens Musikstiftung and the Francis and Mica Salabert Foundation, this work is the last of the Ictus Vocis series in which a close correlation is established between the timbre of the instruments, the gesture of the performers and the melodic motifs. This work is organized in several movements, conceived as so many paintings: Sepideh (Dawn), Nimtāb I (Twilight I), Tābān (Illumination), Bāmdād (Night), Pegāh (Sunrise), Nimtāb II (Twilight II) . In Persian language, Anagrān means infinite light. The piece is dedicated to Eric Daubresse.
