R&P: Can you help me with this?

This weekend, I'm leaving to go on vacation. It's an 18 hour drive. What I need from you is this: Mind-blowing albums. They can be any genre except Pop, Rap, Hip Hop, and new Country. I need albums that could be described as beautiful and awe-inspiring, and could be classified as Concept albums. Albums that will keep you awake, but have moments of melody and harmony that couldn't be considered misplaced at all. Thanks in advance.
