Libertone, who was one of the founders of Spark more than thirty years ago, has taken a selection of his work from the 1970s to the 1990s, most of which has never been shown before, as suggested by the title."Bags Grove," from the '70s, is a showstopper, a funky tangle meant to evoke the visual equivalent of jazz.
There are also a number of neo-deco works related to his masterpiece: the little metal pavilion that sits southeast of Sixth Avenue and Speer Boulevard.
Surrounding the Libertones are McGuinness's lyrical abstract paintings, which comprise natural shapes and muted colors. These paintings were inspired by ordinary sights -- gardens and trees -- but the artist points out that they are based on the memories of their colors, not their forms.
In the north gallery, there's Barbara Carpenter: Morocco: Faces and Places, a small exhibit made up of color images that sometimes verge on being found abstractions.Through October 26 at Spark Gallery, 900 Santa Fe Drive, 720-889-2200, sparkgallery.com.
