MICHAEL NAGLER – Until today I didn’t even know there was such a thing as white supremacist music. Wade Michael Page knew; the “domestic terrorist†who killed six people at the Oak Creek Sikh temple in Wisconsin a week ago Sunday had played in a neo-Nazi band called “Definite Hate†and started one called “End Apathy” in 2005. So Page, when you think of it, has something in common with his immediate predecessor in mass murder, James Holmes, who perpetrated the Aurora, CO shooting two weeks earlier. Despite their differences, in his case also a form of contemporary “art,†namely the Batman film, played some role in the buildup to his murderous violence.
