I personally prefer rock epics, but that could be because I don't listen to albums completely too much, I never really have the time. I think that concept albums are a really great idea though, and I love the material that comes out of them. In a way, they're really 2 sides of the same coin - concept albums are expanded rock epics in a way.
For more concept albums, check out:
Dark Side of the Moon, The Wall, Obscured By Clouds, Wish You Were Here, and The Final Cut by Pink Floyd.
The Incident, and Fear of a Blank Planet by Porcupine Tree.
Almost any Dream Theater album.
Epica by Kamelot.
Deloused in the Comatorium, by The Mars Volta.
For more rock epics, I recommend:
Shine on You Crazy Diamond by Pink Floyd.
The Sky Moves Sideways by Porcupine Tree.
Thick as a Brick by Jethro Tull.
The entire album Black Coulds and Silver Linings by Dream Theater.
Cortez the Killer by Neil Young.
Indian Sunset by Elton John.
Not sure if the last 2 there really fit, but they're incredible songs, and I think everyone should listen to them anyways lol.
If anyone has any more recommendations for concept albums, prog rock, or rock epics, post up! I'm always looking for good, new music.
