CPO is a westcoast rapper, mostly known for his stint on the infamous Death Row Records in the early to mid-90's. You may remember him from 2pac's Picture Me Rollin'.
Foo Nay MiC was an unreleased cut from the Death Row days, that finally surfaced when a canadian company re-released a couple of albums a few years back. Classic vintage west coast beat. Smokin' shit.
Another classic CPO cut.
