Terence Koh detail of Do not doubt the dangerousness of my butterfly song (Silver) (2004) Custom metal vitrine, speakers, ipod with unique song sung by artist, paint, male argyrophorus argenteus butterfly, broken mirror, star dust, 45 " long, 18" wide, 61" tall. Unique

This work is part of the artist's two great current shows, but they close today; my apologies to many people for posting this so late, especially since I've been so impressed with both the work of Koh and, at our remove, that of his gallery, Peres Projects. We visited the space in Chung King Road for the first time just one week ago.
