What do we want and need from our public spaces? As the world emerges from the profound limitations imposed by the COVID-19 crisis, this reader offers a range of possibilities from the domain of art. With contributions from twenty-five leading Australian and international artists, writers, and curators including Cuban artist and activist Tania Bruguera, Indonesian artist collective ruangrupa, British art historian and critic Claire Bishop, and Gunditjmara artist and senior knowledge custodian Vicki Couzens, Let's Go Outside is a timely examination of creative practices in the public realm. From negotiating space in the settler-colonial context of Australia to responding to crises in the United States, Hong Kong, and New Zealand, the reader's essays, case studies, interviews, and visual contributions reveal how ideas and practices associated with remembrance, public history, urban regeneration, communality, accessibility, and activism are challenging and innovating art in the public domain. Let's Go Outside reflects on the growing interest in making and presenting art outside of conventional gallery contexts.
