The bands Drop Dead, Gorgeous; Alesana; The Number Twelve Looks Like You; and Idiot Pilot are touring as a package titled "Fathers Guard Your Daughters." As most of the metal-core musicians here are just past the age of consent themselves, the implication is clear: They want you to think they're debauched and dangerous. Not quite. Headliners Drop Dead, with help from producer Ross Robinson, thread calculated rage through their polished sound; there are no sonic surprises here. They're not, sexy and they're not scary. New Jersey's the Number Twelve are the bill's real highlight, a raging, iconoclastic screamo band with art-punk underpinnings. Punk rock aches when it tries to stretch its atrophied muscles. It's always good to see a band like the Number Twelve tossing the old man out of bed and into some suicide sprints.
