Poa Fm has 7 Ratos de Porão concerts.

Ratos de Porão, or simply "RxDxPx", was formed in November 1981, existing in the Brazilian (São Paulo city) punk rock scene (alongside bands such as Olho Seco, Cólera, Inocentes, Garotos Podres, and Lobotomia). Directly influenced by the UK 82 hardcore bands such as Discharge, Charged G.B.H., The Varukers and Swedish and Finnish bands such as Anti-Cimex and Kaaos, they started to write songs that criticized Brazilian society, a revolutionary concept at the time.
