Led ZeppelinIV (Black Vinyl)

That opening riff on 'Black Dog' lurches and stops and lurches again, a call-and-response between Robert Plant's howl and a band coiled tight as a spring. This is where blues muscle meets English folk mist: 'Stairway to Heaven' climbs from a lone acoustic figure to a guitar solo that still stops rooms cold, while 'When the Levee Breaks' rides a drum sound so vast it swallows everything around it. Four runes, no title, nothing to hide behind but the music. Play it loud and let it flatten you.
