Album list from best to worst - my opinion

Thanks for that. It's always fascinating to read a different perspective. However, I feel you may have run out of steam as you went on, seeing how little you wrote about your top 20 compared to your bottom 13. It'd be interesting if you could expand somewhat on those albums you rate more highly.

Top twenty

If You Can’t Stand The Heat…
In The Army Now
Quid Pro Quo
Backbone
In Search Of The Fourth Chord
Ain’t Complaining
The Party Ain’t Over Yet
Dog Of Two Head
Ma Kelly’s Greasy Spoon
Under The Influence

As I said earlier, the top 20 aren't flawless but most of them are above most other artists' albums in my opinion. I will try to do some quick things with all albums.
Under The Influence isn't bad but the songs are uneven. Still miles above the albums around it. Ma Kelly's Greasy Spoon is a good album, half of it. This is where Quo are trying to find their way. The last song Gotta Go Home is a bit too long, maybe 1-2 minutes could shaved off and Daughter sounds misplaced.

Dog Of Two Head is at the point in my list where I can say with confidence that Quo weren't making anything wrong, unintentionally. Small mistakes are accepted and some songs aren't as good as the others, but this doesn't change much.
The Party Ain't Over Yet is good and could have been great if Stupid Cupid, The Bubble and All That Counts Is Love were cut from it. They are B-side material, nothing else.

Ain't Complaining has made a trip down my list in the last 30 years. I adored it in the beginning, mostly because I didn't know a lot about them back then, and I have a soft spot for 80s productions and songs. The reason it has gone down is that I have heard better albums, that's all. I still think most of the songs are good, but not as good as the songs on the albums I rank above it. Also, I Know You're Leaving and Who Gets The Love aren't good enough for the album.

In Search Of The Fourth Chord and Backbone are two good albums that I feel are overlooked. They aren't similar at all, the former is hard, very tough where the latter is more upbeat, I must say that Backbone is Back To Back if it got better treatment. If all songs were like Backing Off it would have been much higher.

Quid Pro Quo is an album I often forget about for some reason, but everytime I remind myself of it I am surprised of its qualities. One song too many and the remake of In The Army Now is pointless, otherwise very, very good. In The Army Now is the album that got me into Quo, as I have said before, and it still has a special place for me. Maybe I have a bit of a thing for it, but I can only see Invitationa and Dreamin' as the songs that should have been cut from it. Maybe Lonely and Heartburn could have been there instead. If You Can't Stand The Heat... is an album that also have made a trip down the list. I really, really liked it but when I looked at it with more critical eyes I found that the two Rossi tracks on side one were the weaker ones. They're not cut away-worthy, but not as good as the rest of them.


Top ten

Blue For you
Quo
Whatever You Want
Just Supposin’
On The Level
Rockin’ All Over The World
Heavy Traffic
Never Too Late
Hello!
Piledriver

My top ten is written in stone since about 2010, and they're pretty much flawless to me, with slight differences putting them where they are.
Piledriver, I remember thinking A Year was a mistake the first time I listened to the album, but the more I listen to it the more I like it. Still I am affeted by my knee jerk reaction. Maybe a psychological thing here.
Hello! is number 9 because of the dough-like production. Yes, the whole album sounds like a dough. A great dough, for making cinnamon buns, but still rather odd sound to me. Since I'm not a professional musician I don't know the terminology but the album, with Caroline, Blue-Eyed Lady and Softer Ride as exceptions, sounds subdued. The album is fantastic, it's the dough sound that makes it great.
Never Too Late, if the albums were wines, this would be a nice rare one from the back of the racks, the one you take out to show your friends how good it is to have a hidden gem with so many good flavours. It's the kind of album you can play in the background and often people will say: "This is good. Who are they?", and they will be surprised when you tell them.
Heavy Traffic is the latest addition to the top ten, and their best in almost 40 years. Even the "worst" song, Digging Burt Bacharach is great. A little more beef in the boogie section of the song and it would be really great.
On The Level. Just Supposin' and Whatever You Want are where they are because they are so hard to tell apart from each other, in my opinion. They're so good that I have to go into nitpicking to tell them apart. On The Level has that annoying audience chant at the end. Why? Just Supposin' has Rock'n'roll which is good ballad, but a bit repetitive. Whatever You Want doesn't have the full version of High Flyer. They could have added those extra 25 seconds easily.

Quo and Blue For You aren't perfect, but no album is. There will always be smaller things to, again, nitpick on. Hope I have made my opinion clear, and I would love to see how it differs from your opinions.

If I tried this, I'd be here for weeks    Nice to share your thoughts though. 

We'd all have them in a different order; every one of us. And you're right; when you first hear something (i.e. at what age) it has a strange impact on your perception of it further down the line. 

I think I'd probably have 7 of your top 10 in mine. And 8 of your bottom 13 would also match what I'd have. I guess that leaves 8 on which we'd fundamentally disagree. But it's a subjective exercise. There are no rights or wrongs; just opinions and taste. 

I suspect many might have Quo Live as their no.1 but you have only considered studio albums, which I think is reasonable given the proliferation of so many live releases, especially in the last 12 years. And, of course, their sheer similarity. But you did say that you haven't collected everything. Perhaps wisely. I'm not wise. 

Anyone who can liken sounds and production of albums to dough and cinnamon buns and get that into a review is probably worthy of us taking the time to read through their literary works!

As mortified has said, it's a subjective exercise and most of us will agree and disagree in varying degrees, but 10/10 for effort.

Agree that it can be interesting to play the lesser known Quo album tracks, but ones that are often held in high regard by the Quo cognoscenti, to unsuspecting acquaintances, who in turn are then impressed by what they are hearing and they didn't see that coming!  

Ditto with anyone who can get the word "cognoscenti" into a post!

The bit at 2:37 into the solo, that was it, right there....2 seconds and that was all. It actually swaggers into the solo. No one ever does that.
