The CD, which features new music written, produced and performed by Howard, is to be made available in stores and online Sept. 2, the record label said.
Howard is best known for his roles in "Iron Man," "August Rush," "The Brave One," "Hustle & Flow" and "Crash."
"Music has always been the road that leads to where I'm headed," Howard said in a statement. "Film is my vocation, my 9 to 5. In the movies, I'm doing what somebody else is asking me to do. Music is my own personal form of expression. My responsibility, like the sun's, is to shine. Even if the planet is covered with clouds, I must say what I have to say."
