He first appeared on albums from The Beatnuts, on the track "Off the Books" in 1997, and on Fat Joes second album Jealous Ones Envy in 1995, on the track "Watch Out", prior to signing to Loud Records as a solo artist. Big Puns career was cut short in 2000 at age 28 when he died of a heart attack (myocardial infarction).
