“He went for the Guston. He stayed for the Wautier.” That is the way that Half Gallery’s Bill Powers describes the works of Nicasio Fernandez and his solo show, Out of Hand, at the NYC gallery that opens this week. Somewhere along the way to seeing Philip Guston Now at Boston Museum of Fine Arts, Fernandez roamed down a corridor at the museum and came across the 17th century artist Michaelina Wautier, and that struck the NYC artist.
