Black Crowes singer Chris Robinson's voice makes a surprisingly good substitute for Led Zeppelin's Robert Plant, and once you've adjusted to it, Live at the Greek, which pairs Robinson's blues-rock band with Plant's partner Jimmy Page, sounds like one of the best Zep bootlegs you've ever heard. Guitar god Page, after missteps with David Coverdale and Puff Daddy, has finally found a way to bring the big Zep sound back to life, by simply offering faithful renditions of the timeless originals.
