An interesting corollary is that jazz musicians tend to not have as striking an image when it comes to their marketing. Compare what you first visualize when you hear the names KISS or Flava Flav versus say Brad Mehldau or Keith Jarrett. EDIT: This is probably due to jazz musicians taking themselves more seriously and wanting to be known more for their music than anything else. If a jazz artist enlisted Dir En Grey's…
Have you noticed how much more sophisticated Lady Gaga's music is than the rest of what's popular these days? Her popularity has nothing to do with that. It's the way she throws in catchy verbal chants and is equally brilliant at visual and personality branding. And she as a great name.
I find her visual image and brand are very well executed and interesting. However, the quality of her music is just not up to snuff. If you compare her tracks to those of other contemporary pop producers such as The-Dream, Xenomania, and Richard-X, you will find that there really is much room for improvement.
That being said, I am almost certain that GaGa will get her act together and start collaborating with better producers and she will become one of the true great pop artists of our time
