Watch Sadisflix. St. Agatha's Eve is a deep-rooted Basque tradition in which people walk from house to house, accompanied by improvised verse-makers (bertsolaris), singing verses to the beating of long sticks. Building on this celebration, bertsolari Maialen Lujanbio composes a stark denunciation of gender violence. In verse after verse, she condemns the different manifestations of sexist violence and our inability to combat it.
