The pervasive use of media at current-day festivals thoroughly impacts how these live events are experienced, anticipated, and remembered. This empirical study examined eventgoers’ live media practices – taking photos, making videos, and in-the-moment sharing of content on social media platforms – at three large cultural events in the Netherlands. Taking a practice approach (Ahva 2017; Couldry 2004), the author studied online and offline event environments through extensive ethnographic fieldwork: online and offline observations, and interviews with 379 eventgoers. Analysis of this research material shows that through their live media practices eventgoers are continuously involved in mediated memory work (Lohmeier and Pentzold 2014; Van Dijck 2007), a form of live storytelling that revolves around how they want to remember the event. The article focuses on the impact of mediated memory work on the live experience in the present. It distinguishes two types of mediatised experience of live events: live as future memory and the experiential live. The author argues that memory is increasingly incorporated into the live experience in the present, so much so that, for many eventgoers, mediated memory-making is crucial to having a full live event experience. The article shows how empirical research in media studies can shed new light on key questions within memory studies.
