Following the cancellation of numerous events during summer 2020, the Lausanne cultural scene and the City of Lausanne have been mobilized to propose an alternative summer cultural offer, unifying and inviting to a new experience of proximity between artists and the public. A dynamic challenge taken up by all the organizers, artists and collectives in less than 3 weeks to imagine a free program upon registration and to ensure an organization capable of adapting to all safety and traceability constraints of the participants.
