Your favorite 'concept' album

Ok Computer by Radiohead is the ultimate concept album for me. A few others that may not be full-on concept albums but seem to have a common theme from beginning to end are Suburbs by Arcade Fire, Dear Science by TV on the Radio, College Dropout by Kanye West, and The Miseducation of Lauryn Hill by Lauryn Hill.

@pgaulke, I would say a concept album is one that carries a consistent theme from beginning to end, like Pet Sounds by the Beach Boys (another all-time concept album) develops several themes around innocence and the loss of it – the innocence of youth, post-war America, American family life, lost love. By the end, the theme of the concept has been developed sufficiently so that the way you look at it is not the same as when the album started, for example, "Caroline, No" in the Beach Boys example.
