Is this rapper from the movie 8 Mile a real rapper?

So I'm watching 8 Mile the other day and I realize that this guy is good. The guy wearing the white wife beater:




So after looking on IMDB I find that his name is Nashawn "Ox" Breedlove.

Then I go to google but find nothing really about him and no songs; I did find this:

I did also find this, leading me to believe he does have some music:

It says in that big paragraph "Mr. Mozart has also worked with many other artists along the way such as Koffee Brown, Nashawn “Ox” Breedlove, and “Mama” of Ruff Ryders just to name a few."



So if there is any music out there, if anyone could link me to some stuff, send me some stuff, or find some stuff somehow that would be really sick I would appreciate it very much. Thanks.
