Joaquin Phoenix who announced he was retiring from acting in October has decided to take up a singing career. He may have gotten the idea after playing "Johnny Cash" in Walk The Line. In the movie Joaquin sang all of Johnny’s songs and he actually sounded pretty good. In the video below Joaquin launches his singing career in Las Vegas, it seems Joaquin wants to be a rapper. The nicest thing I can say about the performance is that it is sad. At one point he falls off the stage.
