There are three artists with the name Pumpkinhead: 1.) Robert Diaz, better known as Pumpkinhead, is a rap artist who hails from Brooklyn, New York. He has released several albums to critical acclaim, is widely regarded among the underground scene as a great rhyme writer and freestyler, yet has thus far been unable to achieve mainstream success. He first became famous in 1998 with the release of the 12" single "Dynamic," which featured a backwards beat and Pumpkinhead's trademark nasty punchlines delivered in a deep bass vocal tone.
