The Sound of Revolution is a documentary produced by Effetto Espanso, a small independent studio based in Pisa, Italy. It tries to tell the story of Pino Masi, a self-declared "cantastorie", or modern-age minstrel. Born in 1946, he has always been a singer-songwriter following the â€ścantastorieâ€ť tradition. During the years 1966-1969 he took part in the students and workers riots and the birth of the most influent leftist movements. He has always been in the front line when needed, and his songs became the soundtrack of the italian protest during the sixties and the seventies. He has never taken back his origins, and nowadays he keeps singing for peace, for justice.... for a living.
