Songs with an amazing build up

Spanish Sahara by Foals just came on shuffle and it hit that moment and I remembered I had found it on a thread reccing songs with great builds.

So, what songs do you love that either just build and build and build, or slap you in the face out of nowehere, or have a shift where the song suddenly drives, or some other variation?

Edit: Great recs so far! I'm putting everything in a playlist and listening through. Thanks!

Edit2: I've been listening all day and will be listening tomorrow (I have over 120 songs on the playlist) and there are some seriously cool and fantastic tracks!
