Best album opening songs?

I LOVE when a whole album starts off well. Maybe with some kind of fanfare, or just a really good first song. Share your favorites!

Here are a couple of mine: I listened to Avenged Sevenfold's self titled recently and I really like "Critical Acclaim" as an opening song. It really sets the tone for the album! I also really like "The End." as the opener to Black Parade.

Edit: There are SO many answers here that I've never even heard of, clearly I have some listening to do! Thank you all for the suggestions :)
