Albums For The Wall

So I'm finally getting around to decorating my bedroom in my house. I've decided to go with framed record album covers. My criteria for what I hang up are:

1. Has to be an important album in the history of music. Something that influenced music's future in some higher way.
2. I have to like it. I like MOST good albums, so read this as it has to be good.
3. It has to have cool album cover art. Obviosuly, this is a key factor since they are going on display.

The centerpiece in the room is a 3'x2' blowup of "London Calling" and so far I have bought "One Nation Under a Groove" by Funkadelic, "Let it Bleed" by the Stones, "Tommy" by the Who, and "More Songs about Bulidings and Food" by the Talking Heads.

Suggestions?
