Skyros Island, Greece, September 2015
During my involvement in photographing the "deep sky" I missed the accompaniment of music, as my musical experience guides me. So I decided to fill my astrophotos with my music. From September 2016 as a starting point, therefore, together with the Flaming Star Nebula, I present to You, the ‘Floydish Pulsar I’, as my first musical composition (composition, performance and production by me), always inspired by these images.
Parallel Words ! and Dancing Stars I, complete my first trilogy.
Emjoy !
