"Naum Katsenelson's watercolors capture the sights and colors (and I'd swear smells and textures) of his homeland, Russia... Sometimes his landscapes melt almost into abstraction. The landscape may become somewhat mystical, the color more subdued, the brush warm or ere strained... Famous in his own country, Katsenelson has been collected in important international museums. An immigrant to the US, he is still finding his audience here. It is a treat to find him in Denver."
