Giusto Pio (born 11 January 1926, Castelfranco Veneto, Italy - died 12 February 2017, Castelfranco Veneto, Italy) was an Italian violinist and songwriter. He studied music in Venice and later joined the Orchestra Sinfonica Di Milano Della RAI as a violinist. In the late 1970's and early 1980's, he became popular as a long-standing collaborator of singer-songwriter Franco Battiato, who initially hired him as his violin teacher. Apart from working as a producer and musician on several successful albums with Battiato including L'era del cinghiale bianco and La voce del padrone, Pio also collaborated with him as a producer for several singers such as Milva, Alice and Giuni Russo. In 1984 Pio, Battiato and lyricist Saro Cosentino penned the Eurovision Song Contest entry I treni di Tozeur, performed by Battiato and Alice, which finished 5th in the contest and became a considerable commercial success in Continental Europe and Scandinavia. Pio also released two instrumental LP's also in collaboration with Battiato under his own name, entitled Legione straniera (1982) and Restoration (1983).
