The recording of the emblematic Vinícius de Moraes albums in Argentina, popularly known as 'La Fusa', produced by Alfredo Radoszynski with six months difference (July '70 and January '71). For these albums, Vinícius was accompanied by guitarist Toquinho and the voices of Maria Creuza and Maria Bethânia, respectively, in a recording studio with a live, invited audience.

This is considered one of the most significant musical milestones in Brazilian, Argentinian, and global recording history.
