Manns would go on to actively participate in the extensive production of a series of travelling shows called "Chile Rie y Canta" ("Chile Laughs and Sings") which were organized throughout Chile by René Largo Farías. In this early period of his career Manns also composed the cantata "El Sueño Americano" ("The American Dream") (1965), which he recorded with the folk group Voces Andina and that amalgamates distinctive rhythmic elements from different regions of the sub-continent. In this song, which has been traced as one of the firsts cantatas to be heard in Latin America, the historical birth of Latin America is told. Song XII of the cantata "América Novia Mia" ("America My Bride") has been recorded by himself and Inti-illimani several times. During this period he also recorded "¡El Folclore No Ha Muerto, Mierda!" ("Folklore Hasn't Died, Dammit!") (1968) with Silvia Urbina which revived folkloric forms which were disappearing under the influence of foreign musical trends that were being popularized in Chile.
