Folk ballads about murdered women have travelled over time between Britain and America. Many were preserved in the Appalachian Mountains on the USA’s East Coast. In the second volume of her Murder Ballads series, The Positive Reinforcement Campaign (2023), composer Jessie Marino shifts from a playful focus on expanded practice, prominent in her previous output, to reimagining traditional murder ballads using a combination of folk music from Appalachia, electronic soundscapes, Sacred Harp Hymns and structured improvisations developed in close collaboration with the percussion trio Pinquins and Inga Margrete Aas. During the performance, dancer/performance artist Emilia Dorr serves tennis balls into a black abyss, metaphorically and literally voicing anger and frustration through the lens of sport.
