In the summer of 2004, Castillo was preparing for his “Minimalist Reassertions” exhibition at the Glass Curtain Gallery at Columbia College which opened in Sept. 13, 2004. He felt this urge to do a piece (below) reflective of Hokusai’s famous print, “The Great Wave”. He visualized this wave made from twigs. Two of these were done, one in his studio and the other at the Glass Curtain. Little did he know that by the end of the year, he would paint “black waves full of wood” in reference to the chaos of tragic proportions caused by the Asian Tsunami the day after Christmas.
