Paul McCartney
Diversity over time, in both his hits and his lesser known tracks.

Electric Light Orchestra
You always hear something new when listening to their songs.

Pink Floyd/Roger Waters
Great lyrics, great music for any mood

Chicago
The pioneers of using brass to augment cleverly crafted songs (sorry EW&F)

Badfinger/Pete Ham
One of the hidden gems of rock history, Pete Ham and Badfinger had a broad range with great music and thought provoking lyrics.

The Beatles - The White Album
Tons of styles all packed together, and it still works.

Electric Light Orchestra - Secret Messages
ELO's "Sgt. Pepper". Though not as well known as "Out of the Blue" or "Discovery", "Secret Messages" is better produced and more diverse.

Pink Floyd - Animals
Perhaps their "hardest" sounding album.

John Sebben.com
Well, cuz it's my website (:

The Dave Glover Show
A local St. Louis talk show radio host...always diverse and always funny. And you can listen online!

St. Louis Cardinals
GO CARDINALS!
