Born in Madison, Wisconsin, to father Dr. Terry Hexum, a professor of pharmacology at the University of Nebraska Medical Center and cardiovascular and neuroscience researcher, and mother Pat,[1] Hexum went to Westside High School in Omaha, Nebraska.

School led Hexum to music programs, such as Westside Jazz Band, where he met Chad Sexton.

Hexum views his first rock 'n' roll performance as a junior high talent show under the name The Clash.

Other members included Ward Bones, Andy Gray, Lon Breslow, and Ed Birmingham.

Chad Sexton returned from a short stint at University of Nebraska and Unity was revived without Mahoney.

Hexum, Sexton, Ward Bones, and Marcus Watkins formed this new line-up and moved to Los Angeles to make an effort for recognition.

In 1992, the band felt they'd done all they could on the local scene and moved out to Los Angeles to pursue a record deal.

[6] From his own clothing line [7] to his non-profit awareness group,[8][9] Hexum has held many interests outside of music.

The two worlds combined in the early 2022 when Hexum became a Chief Artist at a start-up tech company called SKP.

[10] SKP (a play on the word 'escapee') was designed to help music artists bypass the major label network and find the tools they need without sacrificing their rights.
