1Christopher Lee Rios (November 9, 1971 - February 7, 2000), better known as Big Punisher or Big Pun, was a Puerto Rican rapper who emerged from the underground rap scene in The Bronx in the late 1990s. He first appeared on albums from The Beatnuts on the track "Off the Books" and on Fat Joe's second album Jealous One's Envy, on the track "Watch Out", prior to signing to Loud Records as a solo artist. Rios met fellow Puerto Rican and Bronx rapper Fat Joe in 1995 and made his commercial debut on Joe's second album, Jealous Ones Still Envy, in addition to appearing on a b-side to Joe's "Envy" single, "Fire Water" and "Watch Out."
Later, "I'm Not a Player" (featuring an O'Jays sample) was supported by a significant advertising campaign and became an underground hit. The song's remix, "Still Not a Player" (featuring Joe) produced by Knobody, became Big Pun's first major mainstream hit. His full-length debut Capital Punishment followed in 1998, and was the first album by a solo Latino rapper to go platinum, peaking at #5 on the Billboard 200. Capital Punishment was also nominated for a Grammy, but lost out on the award to Jay-Z's Vol. 2: Hard Knock Life. He became a member of Terror Squad, a New York-based group of rappers founded by Fat Joe, with most of the roster supplied by the now-defunct Full a Clips Crew who released their debut album The Album in 1999. In 1999 he co-starred in the Albert Pyun-directed ghetto-movie Urban Menace, alongside his frequent collaborator Fat Joe.
Big Pun's career was cut short in 2000 at age 28 by a fatal heart attack due to his obesity.
