Portrait of a Ghost NYC artist Dave McKenzie has cast self-portraits of himself as a bobblehead, written letters to loved ones in braille and turned a basketball inside out. In the video piece, We Shall Overcome, McKenzie, who is black, dons a suit and Clinton mask while walking through the streets of Harlem. He navigates the sidewalks in the cartoonish mask, onlookers greeting him with a mix of enthusiastic smiles and blank stares, while a version of the title song plays in the background. McKenzie's work, like all good conceptual art, proves far better at raising questions than answering them. RD

Matthew Picton British-born Ashland resident Matthew Picton has been hyperbolized as one of the greatest installation artists in the country by the local press. While that's a rather ludicrous claim, Picton's road-surface drawings are quite amazing to behold.
