More than a decade ago, Linkin Park sold a couple zillion records by making better-than-Bizkit rap metal and collaborating with Jay Z. They've since wandered the emo wilderness, and singer Chester Bennington is now also fronting Stone Temple Pilots. But on Album Six they're back with a retro-neo-aggro sound that would've been too intense for modern-rock radio in 1999. Tom Morello guests on guitar; the mook-punk yowler "Guilty All the Same" features oldschool rap god Rakim. Even pushing 40, these dudes can still bring it like backward-ball-cap warriors hopped up on Mountain Dew and Dad's fourth divorce.
