I have a very versatile voice and can cover a wide range of styles, as well as having a strong octave range (although that doesn't seem to be an issue for you). Musically, I come from a hip-hop background and have a lot of experience in producing such music. I am capable of recording in a variety of different voices and Chris Brown is one of the timbres I can closely match. If you were to let me know what you specifically need, I'm sure I would be able to help you out.
(Coincidental but unrelated, my middle and last name is Chris Brown. Perfect match!)
