For three decades, Oslo-based collective Verdensteatret have worked to integrate new technology into their performances. Following appearances at the Brooklyn Academy of Music and festivals throughout Europe, they bring HANNAH, their remarkable hybrid of music, installation art, theatre and documentary film, to Sonica for their first ever UK performances. HANNAH was inspired by two trips along the Mekong River, taken a decade apart, and explores processes that are normally so gradual and long-term that they are effectively invisible. HANNAH’s set at first suggests a stylised depiction of the Mekong, with poles that resemble fishing rods or boats’ masts standing upright in a tinfoil water surface. Over the course of the performance, Verdensteatret activate, modify, break up and rebuild this set, while electronic feedback generates constant visual and sonic patterns to accompany the metamorphosis.
