These two complementary works by the Russian composer Alexander Raskatov (composition award of the Salzburg Osterfestspiele 1998) form a real compositional diptych: In "Commentary on a Vision" he links the varying sound aggregates following a sort of dream logic, in which there are no consecutive developments; rather, unforeseeable events appear in a quasi-visionary way from the subconscious and then vanish again. The chamber orchestral work "Xenia" is conceived as it's light counterpart, and is drawn by the ideas of childlike innocence and paradisiacal naïveté.
