The early 1960s saw the rise of social and political popular music, including a vast number of releases by the I Dischi del Sole label. Several important groups had their birth around the same time, including Cantacronache in 1958 and the Nuovo Canzoniere Italiano (NCI) in 1962. The NCI was an assemblage of musicians and composers including Giovanna Marini that made its first major public appearance at the 1964 Spoleto Festival dei Due Mondi and generated a large number of records and concerts.
