I welcome any excuse to play or talk about music, so when I saw 
I grew up in the 70s, but got into music later than some. I did not really buy much until my mid teens. Over the next few years I listened to a lot of stuff and I could probably list 100 albums that had some impact on me, but here is a selection. I have some of them on vinyl and the original challenge was about 'vinyl era' albums, so I will stick with that. They are in no special order.
Anthony Phillips - Sides
This is a fairly obscure one, but I was really into Genesis and he was their original guitarist. Some of this album is similar to their early works, but it has pop songs too. The whole album is on Youtube, but you can find most things there.
Roger Waters - The Pros and Cons of Hitchhiking
I also liked Pink Floyd, but felt they lost their spark when Roger left. Like many of his albums this has a sort of story to it. Of course the cover catches the eye, but there are good songs too. They blend into each other. This particular track gets me each time. I think Eric Clapton does some of his best work on it.
Genesis - Duke
Like Floyd Genesis went through some changes. I love a lot of the Peter Gabriel stuff, but this one has some of their best more pop-oriented songs. I only saw them live much later at Knebworth, but I was into some of Phil's solo work. He can deliver some good vocal performances.
The Police - Regatta De Blanc
They are one of the bands I really regret not seeing live. The songs are great with all sort of interesting arrangements. The solo on this is basically one sustained note.
ZZ Top - Eliminator
I will admit I was not too aware of them before they had huge hits with this album thanks to some cool videos. There is a cool documentary about them on Netflix.
Queen - Queen II
I could go for the obvious Night at the Opera, but I quite like their more prog stuff on the early albums. I did not see them live until 1984. The Bohemian Rhapsody movie is a fun insight (fictionalised) into their early career.
Led Zeppelin - I
This band are a big influence on me wanting to play guitar even if I never quite got to Page's level. The first album has great energy. Of course they ripped off a lot of stuff from old blues guys, but they made it their own.
ELO - Time
Along with Queen ELO were one of the first bands I got into and this was one of the earliest albums I owned. I used to know all the words.
Diamond Head - Cantebury
This was a one-off for me. I had use of the local record library and would grab anything that took my fancy to tape at home (shock horror!). I had not heard this for years, but rediscovered it via Youtube. I do not know their other music if there is more. I think there is a later band with the same name.
Donald Fagen - The Nightfly
This was probably another from the record library. I did not really know much about Steely Dan back then, but this is such a smooth piece of pop.
I did not necessarily go on to play all these types of music, but I have played songs by a fair few of these acts. Ask me another day and I could come up with a different set of albums. These 'challenges' place artificial restrictions that do not limit us in real life.
Find the music that moves you and then find some more. Music makes life better.
