Louisville illustrator August Northcut and his brother, New York photographer Thomas Northcut, have collaborated on an art book titled “The Nod.” It’s about life’s connectedness, said the Northcuts. “This universal phenomenon — it’s about love and friendship and how the internalization of that is shared outwardly, even without words.” The exhibition features photographs, drawings and monoprints from the book. The book release party and reception are Saturday, July 9 from 6-9 p.m. with music by the Weak Signal and Evan Patterson and food by POCO.
