Freire was also in touch with the group of abstract artists around Aldo Pellegrini in Argentina and felt great affinity with concrete and neoconcrete artists in Brazil, like Amílcar de Castro, Lygia Pape, Lygia Clark and Hélio Oiticica, but her work developed its own characteristic style. Freire tended to work in series, taking colors, rhythms and forms as their own subjects.
