Song Dong (b. 1966, Beijing) often explores impermanence and memory through his art, a practice that encompasses video, performance, installation, and photography. Emerging as a member of the Beijing avant-garde performing arts community in the 1990s, Song not only addresses China’s profuse social, cultural, and economic changes in his works, but also often references his personal relationships and experiences, as in the works Touching My Father (1997–2011) and Waste Not (2005).
