The Giraffes have been tearing up venues across the United States since 1996, with their distinctive blend of surf guitar riffs and dark metal machismo (think Dick Dale meets Black Sabbath, but with Ozzy passed out backstage). This is their first show since February, when lead singer Aaron Lazar split from the band, and they decided to go on without a singer. Their instrumental debut will take place at Greenpoint’s best-kept secret, Saint Vitus Bar. The venue is hidden behind a plain black door on Manhattan Ave, with a sign so small you’ve probably never seen it, way down between Clay and Box Streets. The bartenders not only serve up beers, but also sling “St. Vitus Buns” (the options range from “Brooklyn Cheese Steak” to “Veggie Chili”). The metal bar (so metal the second “t” in the St. Vitus logo is an upside-down cross) is a perfect pairing for the metal band. The show starts at 8 and it’s $10 at the door.
