Contributed by Michael Brennan / Anne Russinof passed away a year ago at the age of 68. “Gestural Symphony” is a commanding memorial retrospective of her mostly large, emphatically gestural paintings. Posthumous exhibitions are by nature bittersweet, but Russinof’s resists melancholy because her work is so irrepressibly lively. Her signature outsize curves are sweeping and springy. They kick, bounce, and jump around.
