I recently dug out
Zep III for the first listen in many years. Maybe it was because I was listening to it while I was driving, but damn if it didn't half put me to sleep at times.
The Zep album with the most "legs" to today that I still listen to regularly has to be
Physical Graffiti. By process of elimination, it's probably my favorite.
Speaking of
Houses, though -- did you ever see the BBC TV show "Cooking in the Danger Zone"? Hokey name but decent show. The host, Stefan Gates, is one of the asses on the album cover.
