The performance “Assum Livre” integrates a sequence of artifacts first presented for a PhD thesis, “Backyard of Sounds: A Path to Sound Immersion.” It was recently recreated in a cyberspace event, hence its transcription as a cyberperformance. It consists of an artistic proposal that seeks to reflect on freedom and imprisonment, evoking a metaphor that recreates the experience of the lockdown in 2020–2021. The performance is based on streaming a video recorded with the author and singer performing part of Teixeira's and Gonzaga's song, “Assum Preto,” simultaneously with the live performance of the other stanzas of the song. These alternate with the presentation of the lyrics and the materialization of the performer. As a backdrop, the authors have a projection of natural scenery representing freedom, depicting the natural habitat threatened by human intervention, enhanced by the natural soundscapes, and integrating the hybridization of image, sound, and live performance. Discussion includes the main concepts, the description of the artifact, the developments made, and audience reflections.
