Kollegah

I am not too much into Hip Hop and Rap but there are a few artists that I actually listen to. Including Kollegah.
His Rapstyle is pretty unique and design of "The Boss" too.
While I find most of the German Rap scene to be horrible, Kollegah manages to stand out.
Imperator is a amazing release.

If you don't like Rap much, especially German Rap, give Kollegah at least a listen.
He might change your opinion of it a bit.
