Mario Cascardo’s first few records, under the moniker Mario Maria, already captured a charming kind of Brazilian ingeniousness: João Gilberto-like vocals and airy guitars were filtered and fused through an old, broken laptop. It was lo-fi in the truest sense: not as an arbitrary aesthetic choice, but as the creative result of a technical obliqueness at the frontiers of capitalistic development. Cascardo’s more recent releases as Atletas, like others from his label Municipal K7, provide even stronger evidence that lo-fi is now happening at the margins, where artists are using their own global displacement as blueprint for new musical imaginations.
