The most widely misunderstood, and overrated, Beatles album.
Something I think captures Abbey Road in a nutshell...
They originally wanted to name this album Everest, and the cover photo was going to be the foursome on Mt Everest. Instead they named it Abbey Road and took a photo outside the front door of their studio. Despite its recent critical reappraisal, Abbey Road is not the sound of the Beatles at their creative peak. It's the sound of a band running out of gas, suing each other, and lowering their standards. The Beatles were not trying to make any profound artistic statements, they were trying to fulfill their contractual obligations as quickly as possible so they could move on. All 3 songwriters released better solo albums a year or so after this album came out and, clearly, they were saving their best material.
I should mention I am a Beatles fanatic (not a hater) and can acknowledge the positives here. There are a handful of remarkably great recordings on this album, best of which is "Something." "Something" is an all-timer love song and one of the most mature, elegant miniature morsels the band ever made. "Come Together" is also quite unique -- a post-psychedelic reinterpretation of 50s rhythm and blues with a signature rhythm track unlike anything the band (or really anyone else) had ever done. But alongside these merits are serious problems. "Because" is a virtuosic piece of work, overshadowed by the corny Moog sounds. (The Moog generally does not work on this album, in my opinion.) Similarly, "Here Comes the Sun" is a great song at its core, but it gets bogged down with its overblown prog rock arrangement.
The B-side medley is probably the best example of their misfire and it still shocks me to read reviews from people who think it's some kind of masterful experiment in songcraft. They took unfinished scraps of songs that might have really had an impact if they took the time to work on them (e.g. "Golden Slumbers," "Mean Mr. Mustard"), threw them in the pot with a bunch of other crap, added a Moog and an orchestra, served it up and said bon appetit. John acknowledged many times in many interviews that the medley was pure lifeless junk. And there's a scene in the Anthology documentary where they are re-listening to studio masters of some of the medley orchestration; Paul is absolutely high on his own farts and George looks straight into the camera to say "a bit corny, init?" Yes! It is very very corny. When the theme to "You Never Give Me Your Money" returns as a horn section during "Carry That Weight," I get a full body cringe.
John is only half-present on this album and it clearly shows. There are a number of songs he didn't touch, and he didn't even bother showing up to the final recording sessions. He's also, clearly, not sharing his best work -- most of what he wrote on this album had been kicking around since the band came back from India, and Plastic Ono Band (which is a MUCH better album than Abbey Road) was recorded shortly after this. "I Want You" is the closest thing to a proto-Plastic Ono song on Abbey Road, and it pales in comparison to others in its style (like "Yer Blues" or "Don't Let Me Down"). What we're left with is Paul's ego unchained. The medley has his fingerprints all over it, and "Maxwell's Silver Hammer" is legendary in how badly it pissed off the rest of the band. "Oh Darling" is fine, but it's a weak pastiche at a time when a zillion musicians (including John) were doing a much better job of playing with roots rock n roll revival.
It's been quite surprising to see this album get reevaluated in the past couple decades by younger audiences who have elevated it to "masterpiece" status in the same way the Boomers latched on to Sgt. Pepper. I'm not entirely sure why this is the highest rated Beatles album on this site, but it probably has to do with the cleaner production standards compared to their earlier 60s albums; in the end, I think most people just want easy listening. All in all, Abbey Road showed the way to the future in 70s rock radio, but mostly by influencing its worst tendencies, i.e. corny prog pop and soft rock. This doesn't sound like a band at the cutting edge of popular culture, it sounds like ELO or Wings or any number of yacht rock bands. But hey, I suppose that's also why a lot of people like it -- ELO sold a lot of records.
