Jesse James Dupree is the lead singer and guitarist of the American southern rock band Jackyl from Kennesaw, Georgia.

In 1992, a self-titled debut album was released and went platinum; the band still tours on the festival circuit, in music venues, and on TruTV's reality television series Full Throttle Saloon.

Dupree's most famous routine involves using a chainsaw as a musical instrument during the song "The Lumberjack" and "The Star Spangled Banner".

After performing with Jackyl at Full Throttle Saloon in Sturgis, South Dakota, Dupree formed a partnership with Full Throttle Saloon owner, Michael Ballard, and the duo created a reality show, covering the operations of the largest biker bar in the United States.

Mighty Loud Entertainment manages artists such as Nigel Dupree Band, Jackyl, Wayland, and Babi Mac.
