Phillip Martin III (born January 10, 1968) in San Antonio, Texas, also known by the stage name Nino, is an American rapper, producer, director, screenwriter, film editor, entrepreneur and music distributor.
Martin took on the stage name of Nino as part of the Texas rap group PKO (Pounds, Keys and Ounces).
In the mid-1980s, he made friends with Mark "Magic" Outing and together, along with Robert "AK" Hill and childhood friend Ted "K-Sam" Meadows, they formed the nucleus of the rap group PKO (Pounds, Keys- or kilos, and Ounces, a reference to the weights at which drugs are bought and sold).
In 1992, PKO gained notoriety when CNN interviewed the group about the controversy surrounding their underground hit single Shoot the Police.
After the release of the single, PKO recorded their first full-length EP, Don't Fuck With Texas.
Master P invited PKO to contribute a single to the October 31, 1995 release of Down South Hustlers: Bouncin' and Swingin'.
