Instead of arguing about the Zep and weather or not they are prog, lets just have this thread to talk about our love for the songs that are prog. Its one's opinion if they consider Zeppelin prog and lets just leave it at that...
My fave Prog Zep would be:
Achilles Last Stand
Battle Of Evermore
Kashmir
No Quarter (Song Remains THe Same version)
Dazed And Confused (Song Remains The Same Version) I think that this version is accualy there most prog they ever showed. Especially their amazing rendition of Scott Mckenzie's "San Fransisco" (for all you guitar players out there, the prelude to that section is acuaally the riff from the "I know the way, know the way, know the way, know the way..." section from "Achilles Last Stand" slowed down, which sounds amazing. The Bow solo also is also in my opinion one of the greatest moments in music history!
