Encompassing heavy metal, folk, pure rock & roll, and blues,
Led Zeppelin's untitled fourth album is a monolithic record, defining not only
Led Zeppelin but the sound and style of '70s hard rock. Expanding on the breakthroughs of
III,
Zeppelin fuse their majestic hard rock with a mystical, rural English folk that gives the record an epic scope. Even at its most basic -- the muscular, traditionalist "Rock and Roll" -- the album has a grand sense of drama, which is only deepened by
Robert Plant's burgeoning obsession with mythology, religion, and the occult.
Plant's mysticism comes to a head on the eerie folk ballad "The Battle of Evermore," a mandolin-driven song with haunting vocals from
Sandy Denny, and on the epic "Stairway to Heaven." Of all of
Zeppelin's songs, "Stairway to Heaven" is the most famous, and not unjustly. Building from a simple fingerpicked acoustic guitar to a storming torrent of guitar riffs and solos, it encapsulates the entire album in one song. Which, of course, isn't discounting the rest of the album. "Going to California" is the group's best folk song, and the rockers are endlessly inventive, whether it's the complex, multi-layered "Black Dog," the pounding hippie satire "Misty Mountain Hop," or the funky riffs of "Four Sticks." But the closer, "When the Levee Breaks," is the one song truly equal to "Stairway," helping give
IV the feeling of an epic. An apocalyptic slice of urban blues, "When the Levee Breaks" is as forceful and frightening as
Zeppelin ever got, and its seismic rhythms and layered dynamics illustrate why none of their imitators could ever equal them. [A remastered CD was released in 2014.] ~ Stephen Thomas Erlewine
