Copy that.
Yes, few Floyd fans are familiar with it, but I've owned it on vinyl, cassette, and CD. (I missed the 8-track era altogether, I have no idea what I was doing during those days.)
My first experience with them was Ummagumma, because I had a friend who was going to school at Columbia and was hip to all the new stuff and he turned me on to them. I quickly followed up with Piper at the Gates of Dawn, Meddle, Atom Heart Mother and Dark Side of the Moon. They are all masterpieces. I've listened to all their other albums as well, and although they have their high points, I didn't like any of them enough to actually buy them.
