As art shows abound in the coming weeks (Armory! SCOPE! AIPAD Photo!), we thought we'd get a head start in terms of previews. Plus, Cleon Peterson's awesomely graphic (both the violent and the artistic sense) acrylic-on-wood painting offers just the kind of jolt many of us need to push through these last few hours of the week. Peterson's work will be up in the SCOPE New York art expo, March 26 to 30.
