OK, then. Here’s a brief overview of the discography (I have too much free time):
Led Zeppelin I (1969)
The most blues-influenced album. Setting aside for the moment the issue of Zep’s active and/or passive laxity in crediting their sources, this remains nonetheless a strong “heavy blues” reworking of blues standards and is the basis for what Zep would later (that year) develop into the seminal Heavy Metal sound. Standout tracks include the rock classics “Good Times Bad Times” and “You Shook Me” but also the quieter “Your Time is Gonna Come” and “Black Mountain Side”.
Led Zeppelin II (1969)
Possibly the most well-known album (in that IV is mostly known as the “Stairway” album, not necessarily for its totality). This is the one that cemented Zep as one of the progenitors of Heavy Metal as a rock form, given “Whole Lotta Love” and “Heartbreaker”, amongst others, but note it also contains the more contemplative “Thank you” and “Ramble On”. Also has John Bonham’s signature drum track “Moby Dick”.
Led Zeppelin III (1970)
More folk-influenced and overall a quieter, more acoustic record, but also includes Rock standard “Immigrant Song” as well as what I consider Zep’s best blues number “Since I’ve Been Loving You”.
Led Zeppelin IV (1971)
The “Stairway” album. Also includes instant classics “Rock and Roll” and “Black Dog” but does have quieter tracks like “The Battle of Evermore” and “Going to California”
Houses of the Holy (1973)
A slightly different, perhaps more cohesive sound across this one. “Over the Hills and Far Away” and faux-reggae “D’Yer Mak’er” are classic-rock-radio standards, but for my money, “The Ocean” is the standout track. Also includes John Paul Jones’ signature track, “No Quarter”.
Physical Graffiti (1975)
Double album comprising fifteen tracks, some of which had been recorded for prior albums. As such, it’s a pretty good cross-section of the Zep sound to that point in their recording career. For what it’s worth, when asked which single album would be the best introduction for a new Zep fan, my Zep-head friends and I usually suggested this one (Houses was our next selection, as a single-album non-cheat). “Trampled Under Foot”, “Kashmir”, and maybe “Night Flight” are the radio standards, but also includes (again) a great blues track, “Ten Years Gone”. Oh, and the Richie Valens tribute, “Boogie with Stu” (recorded with Ian Stewart).
Presence (1976)
Recorded and released in lieu of a tour while Robert Plant was recuperating from an auto accident, this one has the Page guitar orchestra piece, “Achilles Last Stand” as well as AOR radio staple “Nobody’s Fault But Mine”. “Tea for One” is the blues track.
In Through the Out Door (1979)
This one is John Paul Jones’ calling card. It’s keyboard-heavy, from “Carouselambra”, “South Bound Saurez”, and “Hot Dog” to the swirling synths of “All My Love”, not to mention the spanish-influenced break in “Fool in the Rain”. Also has AOR-radio classic “In the Evening” and the bluesy “I’m Gonna Crawl”.
1976 also saw the release of The Song Remains the Same, which as mentioned is already available in remastered and expanded form (and worth it if only for the inclusion of the version of “Since I’ve Been Loving You” from the film). Essentially a concert record from Zep’s 1973 tour recorded in New York’s Madison Square Garden, it has the most well-known live recording of “Stairway to Heaven” as well as Bonham’s 10-minute drum-solo workout on “Moby Dick” and Page’s violin-bow epic 29-minute “Dazed and Confused” and the extended “Whole Lotta Love”. The remastered album also includes surprisingly concise versions of “Heartbreaker” and “The Ocean” along with additional tracks not on the original release.
I guess I’ll also mention Coda (1982), though I’m not sure there’s much reason to. I don’t know if Page plans to remaster this one as well, but it’s a grab-bag of unreleased out-takes and alternate takes. Perhaps most notable is a very good version of “I Can’t Quit You Baby”, but the offerings are mostly sub-standard for Zep, and it’s obvious.
