Love Achilles, but sometimes I find it hard to be "objective" about Zeppelin or their albums, since I love pretty much anything they recorded in the studio--even something considered a "throwaway track" like Hats off To Roy Harper...
Usually, I enjoy Achillles better live, but the fadeout on the "Presence" album into that killer bass from For Your Life is tough to beat...
I like just about everything Zeppelin has done too, even PRESENCE and IN THROUGH THE OUTDOOR (I also dig the last 2 70's Sabbath albums with Ozzy everybody seems to rag on). Since I like just about everything, I will tell you the one song I dislike - D'yer Mak'er.
I admit I can tolerate the song more than I used to, but it's still not a favorite. I just never could get into reggae, in general, the beat is too comatose for my brain. Even when the Stones tried it on BLACK 'N BLUE, just.....no. Also, I hate the smug way the band knocks Americans for pronouncing it like it's spelled and not calling it "Jamaica." Like they're in some special club and us peasants don't know any better. Well, like with Chico Marx, the secret password is swordfish....or is that mud shark?
Anyway, love Zeppelin, just not that one song. I'm glad they called it quits when they did too. Actually Diesel, between them and Rush, your two bands, they went out with dignity more than any other band I can think of. KISS and Ozzy they ain't.
