Bold, audacious, and colourful, Joyce Wieland was the first woman living artist to have a solo exhibition at both the National Gallery of Canada and the Art Gallery of Ontario. She was a major figure in the avant-garde film scene of the 1960s and '70s, and together with Michael Snow, she was one of the founders of Canadian experimental cinema. Her work left an indelible mark on Canadian art. Joyce Wieland: Heart On is the first publication to offer a comprehensive view of Wieland's multifaceted career as a painter, experimental filmmaker, and cultural activist. Using her seductive wit as a powerful tool of social and political critique, Wieland embedded disruptive and unexpected elements and imagery in her work with compelling effect. Richly illustrated with over 250 reproductions, Joyce Wieland: Heart On includes texts by curators, scholars, and artists, as well as personal reflections from Wieland's friends and collaborators. Archival materials, an extensive chronology, and passages from Wieland's own writings offer a new understanding of the artist's extraordinary career and the social and political context in which she was creating.
