Monolith # is an interactive sound work by Belgian transdisciplinary artist Roel Heremans, commissioned by and& festival Leuven and later shown at Gare Maritime Brussels. In this participatory experience for four random participants, Heremans invites you on a mental journey through headphones. A voice guides you through thoughts and movements. The text raises questions about the sociological consequences of social media algorithms and briefly brings you back from digital to real life. At the centre is a mirrored monolith: a reference to the many mysterious monoliths that appeared all over the world in 2021 and also an invitation to a contemporary sensory ritual.
