Also known as the "rune" album or Zoso because of the medieval symbols adorning the inner sleeve, Led Zeppelin's fourth album, released in 1971, turned them from mere superstars into giant behemoths of the rock world. On tracks like "Black Dog," "Misty Mountain Hop," and "Rock and Roll," the combination of Robert Plant's banshee wails and Jimmy Page's frenetic guitar playing forever altered the stylistic bent of hard rock music. And the foreboding "When the Levee Breaks" demonstrated that Zeppelin could indeed play the blues fairly straight if they so desired. Still, everything here ultimately took a back seat to the album's (and, ultimately, the band's) magnum opus--the expertly constructed and deftly executed classic, "Stairway to Heaven." --Billy Altman
