The mechanisms of creating percussive sound are so versatile that musicians or composers are far from fully exploring them. The exhibition titled “A double listen”, serving as a dossier, features many of these past aesthetic attempts from performances in a theatre setting: Lam Fung’s “Round” (2016), Austin Yip’s "Urban Construction” (2017), Ken Ueno’s “Mother of Fire” (2018) and Samson Young’s “Glass Chimes” (2019). These multiple endeavours, encompassing traits of quotidian pastime, literariness, metallurgy and engineering, were yet to be wholly unraveled if it is performed and perceived just once. Annotated with decorative embellishment, this exhibition avails one ineluctable gaze, or we phrase it “a second listen”, to anchor all the interconnecting knots in between seemingly separate pieces.
