There was an album called "The North-West Coast Vol. 1" featuring a bunch of dudes from Federal Way, released before "Smile Now...Die Later" that had Tha Loco featured on a few of the songs. Here's an example, the production style is a little different than what we're used to with him but he's still got that same voice, he still is a great guy to have on a chorus:
