River rocks and smoke, stunning work from John M. Cage. This work made on a massive scale with soot from a fire, and watercolors is housed in the Menil Collection here in Houston. First of all, the scale takes this to a new level visually. I have been so fortunate  to be able to view this many times, and each time is special. I connect with this work on many levels, however feel that this is Cage engaging all of his talents in this particular piece.
