If we had proof that Led Zeppelin is a gigantic group, it would be enough to list all the (very) large rock inspired qu''il (Prince, Nirvana, Rage Against The Machine, White Stripes ...). And that IV is the cornerstone of their discography. Not necessarily their best (it ''s Custom II), but the one who have only n''ont qu''un CDs Led Zeppelin. Almost a best of all on its own, this album presents all facets of the group, flattening the riff of "Black Dog," the Celtic sounds of "Battle for evermore" through style exercises ("Four Sticks" where , as its title indicates, Bonham played with four sticks), the homecoming ("Rock''n''roll") to the 'Tolkienesque epic "Stairway to Heaven". Like all CDs Led Zeppelin, it is first the work of Page, who produced, wrote or co-wrote all the musical parts. In full trip "mystical" (he bought and lived in the mansion magician / sorcerer (choice) Aleister Crowley), this CD is therefore a stone temple of the binary (witnesses album titles when a more n''auront simple number "Houses of the Holy", "Presence") that Page will steadily raise in years 70. So Page may well s''offrir blink of an eye his former Yardbirds ("Rock''n''roll"), prick the intro of "Stairway to Heaven" in "Taurus" Spirit, indulge the worst excesses touring under the eye "benevolent" Peter Grant, the Ugly serving manager in the group, strikeout guy in his head with his group produced a colossal music whose influence is steadily be claimed. And to close an old debate of the 70s, you know the groups, aujourd''hui, who claim Deep Purple? Obviously, this "Led Zeppelin IV" is must-have. PS Go take a listen to the version of "Rock''n''roll" by Jerry Lee Lewis on his CDs often did duets "Last man standing" released in 2006. Killer is accompanied by a guitar. .. Jimmy Page.
