Each of these artists was equally or even primarily known as sculptors with deep connectivity to their materials — Serra’s steel, de Maria’s lightning rods, Wilke’s ceramics and bronze, Burden’s vessels and later lampposts. Yet in these videos they each take the opportunity to explore their capacity for performative focus and more ethereal conceptualism. Gagosian online through August 3; gagosian.com.
