Jonas performs in a direct, one-on-one confrontation with the viewer, using the immediacy and intimacy of video as conceptual constructs. Exploring video as both a mirror and a masking device, and using her body as an art object, she undertakes an examination of self and identity, subjectivity and objectivity. Creating a series of inversions, she splits her image, splits the video screen, and splits her identification within the video space, playing with the spatial ambiguity of non-reversed images (video) and reversed images (mirrors). Though Jonas' approach is formalist and reductive, her performance reveals an ironic theatricality. Illustrating the phenomenology of video as a mirror, Left Side Right Side is a classic of early performance-based, conceptual video.
