Composer Missy Mazzoli and librettist Royce Vavrek have debuted a new music-theatre work titled “The Galloping Cure” in Edinburgh, Scotland [1].

The production arrives as part of the 2026 Edinburgh International Festival [1]. By dramatizing the opioid crisis, the work attempts to translate a systemic public health disaster into a visceral, artistic experience for a global audience [2].

Mazzoli said she was driven by personal loss to create the piece. The opera does not present a literal retelling of addiction but instead transforms the U.S. overdose epidemic into a dark, fantastical allegory [2]. The production features performer Daniela Mack and explores the psychological and physical tolls of dependency [1].

The collaboration between Mazzoli and Vavrek continues a creative partnership that has previously seen success in other mediums. This includes a film adaptation of "Breaking the Waves" in 2019 [3].

Critics have noted the production's role within the broader 2026 festival programme, which has highlighted various operatic works this August [4]. The piece uses the stage to examine the intersection of grief and medicine, a theme central to the composer's intent [2].

The opera transforms the US overdose epidemic into a dark, fantastical allegory.

The debut of 'The Galloping Cure' reflects a growing trend in contemporary opera to tackle urgent social and public health crises through non-linear, allegorical storytelling. By moving the narrative of the US opioid epidemic to an international stage in Scotland, the work frames a domestic American tragedy as a universal study of loss and systemic failure.
