As a hotbed of incestuous rock collaboration Louisville is second only to Chicago: the new metal band Dead Child has a pedigree so complicated that the chart on their Web site explaining it resembles a benzene molecule. Guitarist David Pajo, of course, practically constitutes a one-man genre, having played in Slint, Zwan, Tortoise, Palace, and his solo joint M/Aerial M/Papa M, among many others. Drummer Tony Bailey was in M as well as the Anomoanon, Lords, and Crain--the last featuring Dead Child bassist Todd Cook, another sometime M member and a touring member of Slint for their 2005 reunion. That '05 reunion lineup also included Dead Child guitarist Michael McMahan, formerly of the For Carnation (his brother Brian's post-Slint band, which Cook played in too) and currently of Phantom Family Halo, whose vocalist, Dahm, sings in Dead Child. Oh, and Bailey and Dahm were also in Brothers of Conquest together. So what does a group assembled from half the bands in Kentucky sound like? Judas Priest, pretty much. A promised five-song EP isn't out yet, but clips are up on the band's site. Arriver and Dirty Faces open. a 10 PM, Empty Bottle, 1035 N. Western, 773-276-3600 or 866-468-3401, $10.
