Repetitive Motion, an exhibition curated by Jennifer Samet at PROJECTOR Gallery at 237 Eldridge Street, an ancillary space of Steven Harvey Fine Art Projects, brings together eight artists working in a variety of styles ranging from psychedelia to serial minimalism to abstracted naturalism to quasi mystical representation.  They are united, however, in fidelity to painstakingly methodical, rhythmically consistent mark and stroke strategies.  The artists include Ross Bleckner, Glenn Goldberg, Tine Lundsfryd, Amy Park, Barbara Takenaga and Michelle Grabner, curator of the most paint friendly segment of the Whitney Biennial.  Alison Hall, whose San Sebastiano, After Perugino, 2011, derives her stitch-like monotone patterns from fragmented observations of old master paintings, claims dual kinship in her methodology with her farmer and factory worker forebears in Virginia on the one hand and Eastern meditation techniques on the other.  Formerly a traditional realist painter, she also derives inspiration from the late Andrew Forge, the final artist in the show.  Through Sunday.  DAVID COHEN
