please excuse my lengthy post
My favorite used to be Physical Graffiti. Afterall, 4 sides of Zeppelin- how can you beat that? When I was a kid, I would sit listening to that album (my older sister's copy) and inserting the sleeves and insert into the jacket for various window scenes (the buildings pictured on the cover are actually here, in New York City). Not to sound like an old man, but owning it on CD just isn't the same thing to me. I particularly like sides 3 and 4, with "In the Light," "Down by the Seasside," "Ten Years Gone" (love this song- as good as ballads get, in my opinion), "The Wanton Song," "Black Country Woman," and "Sick Again" among my favorite Led Zeppelin tracks. When I think about it, I got really into every one of their albums at some point in my life, with the exception of the 3rd (good album, though).
I am, however, going with Houses of the Holy. For some reason, double albums have always felt somewhat sprawling for me- perhaps because I was so used to 40 minutes of material in a shot. With as many different styles as they attempt on Houses, it still feels really focused. Plus there's not a lemon (song) amongst the bunch. "The Song Remains the Same-" great way to open an album (such energy), "The Rain Song" (another amazing ballad- love the haunting guitar outro), the contrast between the rockin' and non-rockin' sections in "Over the Hills and Far Away," and a tribute to James Brown, for my money, the greatest single artist in popular music with "The Crunge" (I love the fact that the verse is in odd-time but still funky, and that synth line that John Paul Jones plays near the end- so square yet so funky at the same time)- side one is simply awesome. "Dancing Days" is probably my favorite tune on the album- there is nothing quite like that opening guitar riff. The doom-ridden atmosphere in "No Quarter"- a great guitar solo, and the production is first-rate- the way the vocals are mixed, the muddy guitar sound in the chorus, the sound of the guitar in the solo when it's multi-tracked. And closing the album with "The Ocean"- what a great groove! I love the guitar riffs in this song, that moment of barely contained feedback during the first verse, the background vocals, and when they break down into that doo-wop section- too good. "D'yer Mak'er is the only song on the album that down't do too much for me- still good though.
Well, great question Drew. I'm curious to see how other people respond.
