Lied I & II' s period was my way of creating music using traditional instruments with a language away from the post-serialised trend. From 2019 to 2022 I created "complex sound objects" (concept invented by myself), which are intricate sound structures, a kind of "thing in itself", that are to be listened with headphones, in the silence, that is the only way to get the perception of the multidimensionality, the density of the sounds and their motion.
