The Microphone Test series is named after writer Huang Guo-Jun’s work Microphone Test. Two months before Huang committed suicide, he wrote an essay in epistolary style titled“To Mother,” in which he expressed his intention to kill himself to his mother. The writing style is filled with black humor and expressive quality, but he killed himself two months after he wrote this letter, and he did not leave any suicide note. Microphone Test: A Letter to Huang Guo-Jun is a video letter to Huang Guo-Jun. Through conversations with Huang’s works created before he died, the letter depicts private family memories of three good friends, and attempts to portray what in fact belongs to the artist, or perhaps everyone’s memories through the memories of these others. Or perhaps, what is important is not whose memory it is, but the process that memory is constructed and viewed.
