The video is not very easy to understand because it has some background sounds that interfere with the recording. Therefore, I advise you to validate them with more advanced levels, such as C1 and C2.
You can also work on the artist's biography before watching the show and the vocabulary related to city spaces, for example, urban, streets, murals, graffiti, (abandoned) buildings, wall, hole, social intervention, public space, excavation, styrofoam. Also, discuss the surroundings of Lisbon, the south bank, and what can be considered visible and invisible in the spaces of a city; the professions linked to the structure of cities (architects, engineers, bricklayers, construction workers, artists, Mayor, etc.)
You can also work on the concept of contemporary art. And the languages which come from this concept: galleries, exhibitions, artists, independent art, etc.
It would be interesting to ask students about their countries, whether they can see this kind of art in big and medium-sized cities and what they think of these interventions.
Students can also be asked if they can connect with or recognise themselves in the interventions of the artist or other artists.
