P.K.O. (Pounds, Keys and Ounces) was a rap group from San Antonio, Texas. Members of the crew were Nino, Magic, AK & K-Sam.
In 1992, P.K.O. gained notoriety when CNN interviewed the group about the controversy surrounding their underground hit single "Shoot The Police". After the release of the single, P.K.O. recorded their first full length EP, Don't Fuck With Texas.
In 1994, they released The Good, The Bad, The Mafia, which has sold 300,000 units to date. After their CNN appearance, P.K.O. performed with N.W.A, the Geto Boys and Too Short. Master P invited P.K.O. to contribute a single to the October 31, 1995 release of Down South Hustlas: Bouncin' and Swingin. P.K.O. is credited with track #9 on the album, "Got It Sowed Up".
Nino and fellow PKO member "Magic" Mark recorded a diss towards DJ Quik entitled "San Antonio Ain't Shit Like Compton" in response to "Jus Lyke Compton", a track on which DJ Quik compared San Antonio to Compton. The track "San Antonio Ain't Shit Like Compton" appeared on 1994's Tha Good, Tha Bad, Tha Mafia. P.K.O. declined recording deals with major labels and remained an independent label.
Throughout the 1990s P.K.O. released their own albums on their label Youngsta Records. Nino later went solo, and his debut album, Nino, sold more than 100,000 units. P.K.O. is remembered as the Southern/Texas group equivalent to NWA.
