The 2020 edition of the Guide to Contemporary Urban Art undeniably arrives in a unique context with its share of challenges and fears but also with a reservoir of great promises and the genes of renewal. This 2020 edition, like the previous ones, is the result of research, compilations and editorial choices. More space is given to muralists and to artists not or little represented by galleries. About fifty talents who animate the world scene of Contemporary Urban Art are to be discovered or rediscovered.
