Need songs for a long road trip?

I already listen to Red Hot Chili Peppers and The Mars Volta, because I have all of their albums. I'm looking for bands and songs that have a laid back, spaced out feel, almost surreal. They don't have to be upbeat, in fact I'm looking for slower songs. Lastly, I need some road trips songs by At The Drive-In that aren't on Relationship of Command and Vaya. Thank you.
