Why is that “artists” and people out in the world name themselves after people the have no connection to??? Naming yourself after someone who was powerful is not going to sprinkle that fairy dust on you, that sort of thing is passed down in genes not jeans. Unless you share DNA or carry the same last name as the Kennedy’s, Rockefeller’s and the like there is no need for you to be naming yourself after them.
How can you be a real artist or person when even the very essence of what you are trying portray is not really yours? This rant here is not just reserved for questionable artists, if your twitter name, blog, website and/or Facebook is built around images and names that belong to a celebrity or someone else I am also talking about you.
Be real, be yourself.
