Mata-Ratos, a legendary Portuguese punk band, have played in football stadiums, sports halls, bars, performance venues, cultural associations, nightclubs, bandstands, parties and garages. They now celebrate their fortieth anniversary and director Patrick Mendes joins them once again as they tour the country. We find them at Fundão, within the sweaty walls of Octógono, in a concert full of distortion, beer and mosh pits.
