Wear earplugs to the Caledonia Lounge Saturday, when upstart Athens rockers For The Vulture and then terrific Atlanta sludge outfit Hawks will take the stage. But the real draw is the unexpected return of the pummeling, noise-rocking Chrissakes, which has lain dormant since the departure of drummer Rob Thomason a couple years back. The local band's sonic assault isn't all volume-based, though, again, it will be loud; the wiry Thomason's intensely physical playing style, Helen Rhinehart's smoky, pummeling bass action and singer and guitarist Drew Smith's guttural David Yow yowl combine to create an indelible thickness that many "heavy" bands could only hope to achieve. Welcome back, Chrissakes. Stick around for a while, won't ya?
