With return-to-work orders in place and the artworld shifting fully back into gear, ArtReview this month is focused on examples of networks, collaborations, cosmologies and kinship, seeking refresher courses in how to interact with the outside world. Among the people and topics covered: Torkwase Dyson, Jaider Esbell, Deana Lawson, Anicka Yi and the gradual disappearance of an underground art scene in London. Plus columns on racist memorials, environmental catastrophes and the role of technology in creating a sustainable future, and reviews of major art events including the Bienal de São Paulo, as well as tours around Berlin’s and Copenhagen’s most interesting spaces.
