LED ZEPPELIN IV is the definitive Led Zeppelin recording. It was on LED ZEPPELIN IV that the band's sound and concept, Plant's vocals, and Page's arranging skills finally crystallized into something completely distinct and original. The earthy hedonism of their earlier work was deepened and extended on rockers like "Black Dog," "Rock And Roll" and "Misty Mountain Hop." Their interest in traditional folk music (and a more tender form of sentiment) found fresh expression on "Going To California" and "The Battle Of Evermore" (with Sandy Denny of Fairport Convention). And "When The Levee Breaks" was yet another powerhouse blues.

LED ZEPPELIN IV was also the recording which produced Led Zeppelin's most celebrated composition, "Stairway To Heaven". From its familiar opening chord progression, the song steadily grows in intensity, reflecting Led Zeppelin's growing interest in metaphysical imagery, gradually transforming itself from a folkish ballad into a rocking anthem.
