Sound — 10
The sound of this album is brilliant all the way through. Superb riffs like in Whole Lotta Love, Heartbreaker and Bring It On Home along with excellent solos and even acoustic songs like Ramble On. Led Zeppelin have some of the best musicians in rock as shown by John Bonham's long drum solo in Moby Dick and Jimmy Page's flawless guitar work over the whole album. The sound ranges across different musical styles, including blues type songs like What Is And What Should Never Be.

Lyrics themselves don't stand out as much as other Led Zeppelin albums but they go well with the music and Robert Plant is an excellent vocalist and fits in with all styles of music shown on the album.
Overall Impression — 10
I love this album. My favourite songs on it are Whole Lotta Love, Bring It On Home, Heartberaker and all the others really. This is definitely one of the best Led Zeppelin albums, probably the best. If lost or stolen I would buy another immediately and then listen to it. Twice.
