You sometimes hear about concept albums. Sinatra's In the Wee Small Hours is purportedly one of the first of that category. I've often heard it applied to albums that, frankly, don't seem to warrant the label. Our 4th best album of all-time, however, most certainly does. #4 - Art of Noise - The Seduction of Claude Debussy (1999) The last studio album of the Art of Noise finds them exploring the concept of the life and work of composer Claude Debussy, concentrated into a one hour, thirteen track album of synth, rap, hip hop, drum n bass, classical, and opera. It is unlike any recording I have heard before or since. And, if anecdotal conversations are anything to go on, during the nearly twenty years since its release, not enough people have heard of it.
