If

Although it sometimes seems as though it's not possible for a Pink Floyd song to fly under the radar, it's in fact very possible: few of the albums before Dark Side of the Moon are really well known even by a lot of Floyd fans, other than by name. I mean, sure, every serious PF fan is well aware of Piper at the Gates of Dawn, but without even a shred of evidence I'll state that I suspect few have heard it even once, much less ten percent as often as Wish You Were Here.

The same very much goes for their delightful soundtrack albums, Obscured by Clouds and More, and to a (much) lesser extent Atom Heart Mother and even Meddle.

Which is a shame, since they both are worthwhile albums—especially Meddle, of course—even if Atom Heart's title track is the weakest song on that LP.

I'm not sure this is the strongest, but it surely is daggum purty. (Nearly as attractive as the record sleeve.) Roger Waters' writing isn't nearly as sophisticated as it would become just a few years later, and his singing verges on being a bit precious, but the music's just lovely, and the lyrics casually introduce, long before Dark Side of the Moon, Wish You Were Here or The Wall, the insidious way insanity can creep into one's brain. Shades of Syd and crazy diamonds.
