You're not a moron for wanting to listen to more Pink Floyd! You're awesome!
I've been absolutely obsessed with the Floyd for over 20 years, so I'm pretty qualified to give you my 2 cents.
American classic rock radio will only play tracks from
Dark Side, The Wall, Wish You Were Here and occasionally
Animals. So the northwest coast is not an anomaly.
These albums were released during the 1970's after the astronomical success of
Dark Side of The Moon. Most people regard this period as their most creative, as it was also their most commercially successful.
But there was life before
Dark Side for the Floyd! Seven albums to be exact.
So having said that, I'd recommend listening to
Dark Side, Wish You Were Here, Animals and The Wall thoroughly(if you haven't already) before working your way backwards through their catalog beginning with
Meddle, Obscured by Clouds and Atom Heart Mother.
After that's digested go back even further to
More, Ummagumma, and Saucerful of Secrets.
And then after that introduce yourself to the works of Syd Barrett with
Piper at the Gates of Dawn
Enjoy!! and any questions, we're always here to help.
