Favorite Led Zeppelin Album

Seconding the vote for Physical Graffiti, with Houses of the Holy not too far behind.

Led Zeppelin II, followed by Physical Graffiti.  However, I can spin about any album and be happy.  Ramble On!

I got Led Zeppelin IV cassette one year for Christmas, probably mid to late 70's. The cassette was bright pink in a black plastic case with the small but still cool album art on the plastic box. 

I played that cassette over and over on a mono Panasonic cassette player.

It's probably my favorite by a slight margin over Physical Graffiti. I will confess that the famous Stairway to Heaven, while I appreciate it, I skip over that song.

III.  Gallows Pole is probably my favorite song.

First and House of the Holy.   What a great band that actually evolved and still produced amazing music.  Physical Graffiti was DIFFERENT and took me a while to fully appreciate, but it is awesome as well!
