San Francisco artist Rex Ray, who used to live in Colorado, has become a hot property over the past few years. Fortunately, Denver is one of the spots where his remarkable signature style is regularly highlighted. Ray's work riffs on mid-century modern, using organic shapes in cut paper arranged in the manner of abstract landscapes. For most of 2009, a Ray mural hung in the Promenade Space at MCA Denver, surrounded by wallpaper that he also designed. Both elements were created specifically for this show, a solo tour de force curated by former MCA director Cydney Payton, who returned to the museum to do it.
