What CD/album by a major artist do you feel is really great, but has been overlooked by more popular sellers?

Sometimes major artists will breakout with really great songs and the ones that get airplay (or are picked up by films) are what become popular. But what about obscure or less well-known CD’s/albums by well-known artists that you feel are brilliant, but not as well known and worth a listen?

For example, “Songs for the New Depression” was not a very popular album by Bette Midler when it was released. A throwback to the 40’s with some old re-styled classics, it is Bette at her best. (That’s one I thought of off the top of my head.)

What are your favorites and forgottens?
