That’s no surprise as “Another Brick In The Wall” is kinda Floyd’s Disco song. Maybe more on the funky side with the bass line and rhythm guitar, but it definitely owes more to Chic than to, say, Chuck Berry.
ETA: a similar song by a rock band is Queen’s “Another One Bites The Dust”, which hasn’t been mentioned so far. And yes, “I Was Made For Loving You” is also a Disco song to my ears.
I always figured the backlash against disco was mostly due to a general mid-late 1980s and 1990s backlash against the 1970s/early 1980s exuberance. Pretty much anything 1970s was looked at as hopelessly dorky and goofy by that point. It was basically our parents having tried to be cool, but having done so in such an over the top and ridiculous way, that anyone below a certain age was disdainful of that.
And I suspect that the 1970s stuff was like it was for the same reason- our parents were essentially separating themselves from their parents and their staid 1950s/1960s music and social mores.
To my ear, it seems to have about the same relationship to modern day dance music as rock/metal do to grunge- i.e. clearly descendants. I mean, I’m not at all sure how you can hear actual disco music and not hear its echoes in today’s dance music, just like there’s no way on earth you can hear grunge music and hear echoes of all sorts of metal and rock.
Now why rock as a category(including grunge) basically petered out after about 1993-1994, I don’t know. I suspect that it’s because younger listeners didn’t listen to it; taking my experience as someone who was a rock/metal/grunge fan in high school through college (1987-1995) with a brother who is seven years younger, I think it’s because rap/hip-hop/R&B became much more prevalent in that crowd at about that time. I mean, I listened to metal, grunge, etc… and some rap in my teens/early twenties, but my brother didn’t- for his generation, it was all rap/hip-hop/R&B from their early years, and it hit its stride in the late 1990s/early 2000s
[Chortle] Maybe by a huge stretch of the imagination. And the edited 45rpm version at that. But certainly not the album version.
It was still a weird song to play in the Disco I was in at the time in 1979. That place usually didn’t deviate at all. And watching people trying to Disco dance to it was doubly weird.
Forgot one of the most bizarre songs to come out of the disco era: Stars on 45. Their disco version of a medley of mostly Beatles song was a hit.
Radio version
Yes, there was an extended version to be played in discos.
You’ve been warned that you can’t unhear the sheer horror of these songs!
Sigh, this is becoming another entry in the ‘Threads which shit on my playlist’ bookmarks folder. 
No, not really a stretch in my book, the rhythm of “Another Brick In the Wall, Part 2” came straight from Chic’s, Bernie Edwards’ and Nile Rodgers’ songbook. There were two other parts of that song on the “The Wall”, those two sounded very differently, but the hit version hit close to Disco’s home. As I said, maybe more on the funky side, but the line between Disco and Funk was always blurry anyway.
Yea, the mid 70s was sort of a low point for rock music. Much of it had evolved into a more “safe” and “easy listening” style that didn’t scare your parents. Stuff like Fleetwood Mac, The Eagles, and Billy Joel. Rock became mushy, stagnant, and insipid. And then there was prog rock, which emphasized the music itself (for better or worse) instead of the overall message and attitude of rock ‘n’ roll.
A lot of people in the late 70s didn’t like the direction rock was going. I think disco was simply the last straw for these folks.
A number of years ago a rock writer wrote something along these lines:
When The Ramones came on the scene, it was like a bowling ball being dropped on a box of powdered donuts.
I think it perfectly describes what happened when punk rock came into existence. And I think the “why” is obvious: some rock fans wanted rock to be dangerous again, hence the birth of punk.
(I wish I could find the exact quote. I tried Googling it, but couldn’t find anything. I think it was in the Top 100 Rock Albums list in Rolling Stone magazine, in I think 1987.)
I would say rock lasted a little while longer until it finally petered out at the end of the decade/century/millennium. As to why it did, there’s a short, superficial reason and a long, detailed reason. Short and superficial: Kurt Cobain shot himself. Long and detailed: the alt rock/grunge revolution was eventually brought under control by the music industry which had earlier been caught off-guard by its sudden explosion in popularity in 1991. The immediate result of this was the bland aural paste that was grunge-lite and alt-lite. The music had lost its edge and that’s why listeners like your younger brother went over to hip-hop/rap instead. While this was going on, there were a number of things happening that further had adverse affects on rock. One was the continuing balkanization of the the music audience into smaller and smaller niches. Another was the passage of the Telecommunications Act of 1996 which, among its many negative effects, resulted in media megacorps like Clear Channel (now I 
Radio) monopolizing radio at both local and national levels. Control was centralized, formats became even more rigid, and playlists were standardized and ruthlessly culled so “outlier” songs or artists had little chance of getting airplay. A third factor was the orgy of mergers and acquisitions within the recording industry during the decade. All those buyouts cost a lot of money and that money had to come from record sales. So, the blockbuster mentality took over resulting in record companies having little patience in acts that had modest sales but loyal followings. Artists were culled from company rosters and many of them were rock or alternative acts. Finally, and most significantly, there was the rise of the internet and the MP3 format. In the late 90s, many listeners of rock were tired of having to rely on Clear Channel-controlled radio stations or getting gouged at the record store for their music so they started ripping and exchanging it (illegally) on-line. The fact sales of rock CDs went down and internet downloads increased is not a coincidence since rock listeners were more likely to be tech savvy than fans of other types of music like teen pop, country, or hip-hop who still bought their music at brick-and-mortar retailers. From the perspective of the music industry, this meant rock was in decline so attention and money was shifted to other genres.
And also older in addition to being tech savvy. Being older means they were likely to have DSL or other access to high speed internet.
A middle school or high schooler into the current pop music probably didn’t have high speed internet, dial up was still common into the Bush presidency.
That is mind blowing.
Boston.
Frampton Comes Alive.
The Commodores.
There’s good music in any era I think. Hmm, I need to leave a video here…ok, great vocal performance!
A generation later, Sebastian Bach described the rise of Nirvana and grunge as “a musical enema”.
These people have such a gift for words…
BTW as a former 80s College Radio staffer I salute your avatar, sir.
True. They were better prepared for it. As you say the industry had intensely re-corporatized by the mid-late 90s – and Punk/New Wave had quite benefitted from a larger segment of independent labels c. 1980.
Oh absolutely – but part of what may have been going on with the Disco Sucks “movement” was that towards the late 70s at least in the USA, there was this audience that was feeling unrepresented. Though for a long time the charts and labels tended to be uncaring of what for lack of a better term you could call “working class rock” (which was an artifact of it just not being as hit-singles oriented as pop and R&B), it was towards the tail end of the disco era that some people got extra snippy about it and saw disco as the scapegoat.
Maybe, maybe not. My place of work subscribes to Mood Music (nee Muzak), and usually plays The 70’s Channel. I hear lots of ABBA, Bee Gees, and Melanie; I can count on hearing Gloria Gaynor’s “I Will Survive” at least once a day. The balance is yacht rock, Gordon Lightfoot, and The Eagles. No Stones or The Who or AC/DC or anything I’d call “rock”.
Oh, having mentioned the connection between funk and disco, the Stones established a disco/funk vibe even before “Miss You”. “Hot Stuff”, the Stones, not Donna Summer, anyone? That was Mick, he brought in the funk, and Keith brought in reggae.
ETA: my point is: however much you still hate disco, almost all of your favorite classic rock bands did disco songs in the seventies. Even Zep.
For me, personally, it wasn’t that I dearly loved plain I-VI-V chord Bill Haley style rock-n-roll and hated disco. It was that I dearly loved complex ethereal Pink Floyd, Yes, Alan Parsons Project, Tangerine Dream, etc, and large-sound symphonic-influenced progressive stuff like Styx and Kansas. And disco had pushed all that off the air. I lived in a low-population-density state and there were a limited number of radio stations. Disco ate most of them.
I would not have been happy if an upsurge in country music had done the same, or rap, or even a lineup of Bill Haley style rock for that matter. (I am fine with a mixed assortment that includes some Stones and Bob Seger, but I sure wouldn’t trade Pink Floy’d “Dogs” for “Jumpin’ Jack Flash”, know what I mean?)
I don’t think the basic conventions of disco music are unreconcilable with good music. Pink Floyd’s “Another Brick in the Wall” has already been mentioned, and I’ll add Alan Parsons Project’s “In the Real World” as another example.
But it tends towards overly repetitive with way too much boomp thump boomp thump beat that gets under my nerves; the genre has its own recurrent trends, certain instruments and certain vocal stylings. Most of it I don’t care for.
What? Carouselambra? Hardly.
I think that much of the “In Through The Outdoor” album has a disco vibe. It was recorded in the ABBA studios, if that matters. There had been earlier forays into that direction with “The Crunge” and “Trampled Underfoot”, but those were more funk than disco.
I have fond memories of “Disco Duck” myself. But that probably has more to do with the clever arrangement a particular young lady performed at a West Texas strip joint back in the day. It was both amusing and erotic.
Steely Dan didn’t. (I know you said almost.)
For me, the death of rock was simultaneous with the death of MTV. That came on air in 1981 but didn’t go national until 1982. Most of the groups making videos were British new wave and so they dominated early programming. MTV at first didn’t play punk or hip hop or disco (or funk or soul or country or a lot of other genres). It gradually expanded to include Michael Jackson and Van Halen and Talking Heads and then added specialty programs on rap and alternative and a few other genres. New acts broke on MTV or they didn’t break at all, and heartland teens were introduced to some wonderful British groups which otherwise never had a chance. A mixed blessing, to be sure. Nevertheless, MTV ruled music.
When it stopped being all music videos all the time - early 90s, IIRC - the piston that drove rock music vanished into smoke. British bands didn’t break out the way they had been. Post-Nirvana rockers didn’t want to be seen on MTV in the first place. The national audience splintered into tiny pieces. The number one albums were from a dozen different genres. Instead of every generation throwing a hero up the pop charts, every fanbase did every month or two. By the end of the 90s it was almost impossible to imagine a rock group on top; they were rare exceptions. Kids didn’t get together to form groups. They were individual singers planning to be stars. Rock never recovered.
