A common theme among great musicians and their albums is that they are rarely directionless. If an artist fails to change his or her tune for years, it’s going to become stale no matter how good it really is. An evolving sound — and with that, an image — turns a good band into a great band and a great band into the stuff of legend. Do you think the Beatles would be as well known if everything they wrote sounded like “Love Me Do?” At the same time, a change in musical direction doesn’t have to be inherently significant to the artist. Oftentimes it’s just what they feel like doing.
