Multi-Grammy-winning '80s hitmaker Pat Benatar, a pioneering woman in rock, is about to go into the studio to record her first album in nearly 20 years. In the interim, she's raised a couple of daughters with husband Neil Giraldo, who's also her producer and collaborator. He'll join her for an intimate evening at the 9:30 Club tonight. To paraphrase a few choice hits, they're sure to hit you with their best shot in the shadows of the night, proving that love really is a battlefield, full of heartbreakers. Tonight, Tuesday, July 19. Doors at 7 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $45. Call 202-265-0930 or visit 930.com.
