Some flawless bangers on this album, but probably one of Zep's weakest albums. Rock and Roll has been overplayed and used in too many macho truck commercials for me to care. Stairway to Heaven, pretty lame and boring until the last 90 seconds of the 8+-minute track ...and that's a long time to wait for the good parts! Evermore, lame, cry me a river in middle-earth, Robert. Four Sticks, ugh that dumb repetitive bassline. California, snoozer and Levee, meh. The real gems here are Black Dog and Misty Mountain. I mean, DAMN! Misty, Mountain... ? You are a golden goddesss.
