Let's get a working definition of a 'concept album' : "In a concept album…all songs contribute to a single overall theme or unified story." "Pet Sounds", Sgt. Pepper, "Dark Side on the Moon", "Double Nickels on the Dime", and "Ok Computer" are just some of the concept albums that people will debate for inclusion into the best of the best list. I'd like to put a new album, available online, into consideration: Denis Marshall's Betrayed. The unified story? The story of how Denis Marshall's ex-girlfriend gave him herpes.
