Hard rock perfected! It's around Led Zeppelin IV you can easily say that the group moved up from being incredibly great to flat-out legendary. On IV, they do a bit of what the did on each of the three preceding albums, but rather than starting to repeat themselves, they get better! Amazing. Every song a classic: "Black Dog", "Stairway To Heaven", "Rock And Roll", "Misty Mountain Hop", "When The Levee Breaks", "Going To California", "Four Sticks" and "Battle Of Evermore". © 1996-2014, Dusty Groove, Inc.
