So many good Zeppelin songs, but here's a few ones anyway that might give you a slight overview: Stairway to Heaven (classic among classics), Achilles' Last Stand, Rock 'n Roll, Black Dog, Immigrant Song, Friends, Good Times Bad Times, Dazed and Confused, Moby Dick, Over the Hills and Far Away, Misty Mountain Hop, the Battle for Evermore,...
But try to stay in the stuff they did with Bonham. Post Bonham stuff is practically worthless.
What's your opinion of this legendary band? favorite CD? overrated? any comments welcome
