Today, moving image arts are no longer defined by conventional classification and genre, nor are they bound by preexisting theoretical frameworks. In the past few decades, the relationship between documentary and contemporary art has also transformed significantly. Showing artists’ documentaries has become commonplace for biennales keen on addressing diverse political viewpoints. An instance of such boundary-breaking work is Realm of Reverberation (2014-16) by Taiwanese artist Chieh-Jen Chen. Realm of Reverberation blends fact and fiction, politics and poetry, history and imagination to narrate a story on the patients, volunteers, immigrant brides, and the ghost of a prisoner of conscience in the Losheng Sanatorium. To provide a forum for public debate on the controversial conservation/demolition issue of the Loasheng Sanatorium, the screening of the work always includes speeches and related exhibitions. Nonetheless, Realm of Reverberation is not just a documentary with a grand narrative; it also displays how Chen’s “visceral feeling” led him to engage in politically-themed art. This paper will examine the key concepts in Chen’s works: The Sentimental Genes in Malfunctions No.3 (1983) and Flash (1984), the “aftermath effect” in Lingchi (2002), and the “reverberation” and “yaoyan films” in Realm of Reverberation, to argue that Chen’s experiments on shaping political action through contemporary Taiwan art powerfully manifests the trend of trans-disciplinary moving images.
