SONAR

ouvirOUver, 2020
As composições sonoro-visuais de O Grivo possibilitam múltiplas experiências numa relação entre música, instalação e performance. As esculturas sonoras inventadas pelos artistas, a partir de fragmentos, impressionam não só pelas formas, mas também pela presença que assumem no espaço, criando uma territorialidade expansiva que transita entre a gambiarra
