In the planning phase of this CD, which evolved together with the talented performer Miriam Garagnani playing the acoustic part of compositions on the piano with great virtuosity, it was decided to create a musical path that included the double version of two previous compositions of mine: Achernar (2014) for piano and orchestra and Nan (2019) for solo piano. It is the new interpretation of two particularly relevant songs which can best summarize my musical poetics, experimentation and research work as well in the years 20142019, especially on the piano - but not only it, together with several masterful performers. Nan (2019), for example, is a composition created for pianist and researcher Giusy Caruso, a performer mostly committed to playing music of the present day. That composition is proposed on the CD both in the original 2019 version for solo piano and in the 2024 version for spatialized piano, while Achernar (2014), originally composed for piano and orchestra, is presented in two recent 2024 versions, the first one for spatialized piano and the second one for piano and 'imaginary orchestra.' The second version has been a chiseled work in which we wanted to recreate a sort of electronic orchestra starting from the acoustic sound of prerecorded and electronically processed piano. With the aim of achieving that particular sound result, we worked on modifying the previously recorded audio material with the help of various sophisticated audio editing tools.
