There isn't really anything near the airport. Since it is kinda in the middle of nowhere.
If you are looking for hip-hop there are all the bars in LoDo, that would be the area just south of Coors Field. Most of the bars there play a mix of hiphop.
There is quite a bit of hip hop stuff if you go south of colfax.

I'm sure there are a few more places around Denver too. These are just the hip hop places I know of off the top of my head.
