Looking to albums like pain of salvations be, ayreon, an album based around a whole concept

There is a thread dedicated to progressive metal recommendations. Your post does not make it clear whether you're looking for prog metal concept albums (seeing as your examples are such, it could be assumed, but nowhere do you state it). You should've titled your thread based on the criteria you have, whether its the subject matter of the concept, the music style, or a combination of certain elements. If you have no specific criteria other than that you're looking for concept albums, it's rather pointless to make such requests. There are probably thousands of concept albums.
