His name is Italo Vegliante and he’s an Italian actor and guitarist who has acted as a feature character in Italian B-series films during 1981-1986.
Italo performs various melodies and sounds of Ennio Morricone (famed Italian composer) using only a classical guitar and his mouth! It’s super impressive!
All of the sound effects and instruments (minus the guitar) are done using his mouth.
