I adore the diverse styles and consistent quality of The Beatles (White Album).

“Nobody Home”

Well, it was released as a promotional disc, but not till ’72:

In any case, although they didn’t specifically craft singles, that doesn’t mean Atlantic records wasn’t going to issue them! http://rateyourmusic.com/artist/led_zeppelin#Single

And speaking of singles, how the hell did “Hey Hey What Can I Do” get relegated to B-Side status?! I’m glad it’s readily available now, but that was a pretty unjust decision for music fans. Would’ve fit in nicely on III.

The Beatles [White Album]

As a pioneering British psych album putting tracks like “Take Up Thy Stethescope…,” “Bike,” and “Interstellar Overdrive” on the same disc, Piper At The Gates Of Dawn gets my vote!
