Say the name Dick Dale and a sound instantly springs to mind: a huge, reverberant guitar burst that evokes the whoosh and howl of waves and wind. It's the sound you hear on dynamic '60s hits like "Misirlou," which many know better as the main theme for Quentin Tarantino's 1994 movie, "Pulp Fiction." It's the sound that defined surf music. And it's a sound Long Islanders will get to hear up close tomorrow, when the 77-year-old Dale performs at the YMCA Boulton Center in Bay Shore. The man himself describes it best: "When I come onstage, I'm exploding."
