Again I'm old enough to remember buying Pink Floyd albums as they came out. I'm glad you're discovering them. As you say musical diversity is key really - I love all sorts folk; rock; classical; jazz; blues; etc. etc.
Have you tried Cat Stevens? Catch Bull At Four.
I was fortunate to live through the whole of Queen's reign. I went to their free concert in Hyde Park in 1976 - my sister was more of a fan at the time (which partially influenced me) I was less 'commercial' but looking back they've made some fabulous music - just wish Freddie was still around.
The Dandy Warhols At the time loved Bohemian Like You and thought they were a one-hit wonder. Then found You Were My Last High six months or so ago which led me to find tracks such as Sleep; STYGGO; Mohammed; Talk Radio; Godless; You Are Killing Me etc.
Marillion loved them first time around...
