While I like DIY stories a lot, I will mention that
LA Woman has never once been mentioned as a recording of comparable quality to
Dark Side of the Moon.
There have been some great records made in weird places, including some of my favorites. The Band recorded Songs From Big Pink in a big old pink house in Woodstock, NY. Springsteen's Nebraska was a super cheap home recording; effectively a demo. The Rolling Stones Exile on Main Street was recorded in a mansion in France. Radiohead recorded OK Computer in an old house (and that's a great sounding record, though not as good as The Bends that preceded it).
Many of my very favorite records are 80s punk rock records, and nearly all were recorded in extremely suboptimal conditions (nearly all engineered by a guy named "Spot").
All that said, it's clear when a recording is of the caliber of Dark Side of the Moon and it's extremely rare. It doesn't mean we can't love less amazing recordings. Just that there is an artistry and science to audio recording, on top of the artistry of the music being recorded. And, it's usually a major undertaking to achieve something like DSOTM. The pantheon of god tier records, where literally everything came together in a near-perfect work, is pretty small. I'd probably include some of the following (for reference): Fleetwood Mac's Rumours, The Beatles' Abbey Road, Peter Gabriel's So, Bjork Post, Michael Jackson's Thriller, The Flaming Lips' The Soft Bulletin, Marvin Gaye's What's Going On, Steely Dan's Aja, Outkast's Speakerboxxx/The Love Below. There's more, of course, and it's debatable what qualifies...the more live instruments and musicians on the record, the harder it is to make it perfect, but all of those are worth a listen for their production qualities alone, IMHO.
Most impressive may be artists that make amazing sounding records with very limited resources. Bon Iver's For Emma, Forever Ago is perhaps the archetypal example of this. Recorded in a cabin by one dude with very limited equipment, but it sounds incredible and holds up very well to repeated listens.
I could ramble for days about production quality and my favorite records...
