Hard rock perfected! It's around Led Zeppelin IV that you can easily say that the group moved up from being incredibly great to flat-out legendary – really in a class by themselves, although maybe they'd already reached that point with the sublime sounds of the previous three records! There's a darkness here – and a sense of magick too – an eerie new energy that still has all the balls-out rock power of before, but which has the group moving into this heady territory that's really all their own. Every song is a classic – and tracks include "Black Dog", "Stairway To Heaven", "Rock And Roll", "Misty Mountain Hop", "When The Levee Breaks", "Going To California", "Four Sticks", and "Battle Of Evermore".
