The song they were singing, “Un Violador en Tu Camino” (which translates to “A Rapist in Your Path” in English), was written by LasTesis, a feminist performance group based in Chile. It was first performed publicly in Chile in November 2019 in the midst of the country’s nationwide uprising against inequality.
