The Documentary is the kind of album that deserves to be celebrated on its tenth anniversary. That's exactly what happened last night, with The Game holding a special concert for his biggest contribution to Hip Hop history.

The 35-year old had promised there would be special guests at the Los Angeles show.  He delivered with West Coast legend Dr. Dre and the current king of LA (and maybe another famous city) Kendrick Lamar.

Dre, The Game's mentor, didn't do any rapping because that's no longer what he's really about. K.Dot jumped on 50 Cent's  'Westside Story' verse. Check out the visuals below.
