Here's a version in easier-to-understand English: The 2nd artist is Mexican, Francis Alys, whose work, like X's, is also driven by "street activity and performance," but here the actions are more systematic and structured. Alys' work presents incursions into the cityscape, based sometimes on his observations of existing patterns of behavior (without his participation in the action) - for example, the observation of particular movements of pedestrians over time - but more often, on the instigation of some form of stimulus, provided by Alys himself as he walks through the city, or by other specific individuals or groups, which creates a performance of some sort.
