Courageous songs for confused times: The sixth album by Da Cruz, who comes from São Paolo and lives in Bern, is called “Baladas da Luta” (“Ballads for the Fight”), and that’s exactly what it sounds like. It is deep, urban music in attack against hatred, delusion and political shortsightedness. It is a musical reappraisal of the last four years, in which Brazil has undergone an uncanny political and social transformation.
