With over 20 years in the music business as an executive at some of the most prestigious major record labels in the world, it is no wonder why this tastemaker has been sought after by the music industry's elite. Big Billy Clark started out his career at Def Jam Recordings in 1994 when then CEO Russell Simmons recruited him into their west coast office. Clark hustled his way from intern to Senior Director of A&R/West Coast Office Manager. Clark was given the responsibility of running the west coast offices daily operations on top of being a creative executive that could sign and work in various capacities with some of the labels biggest artists which included Ja Rule, Ludacris, Jay-Z, DMX, Method Man, Redman, Mariah Carey, Hoobastank, Christina Milian, Bon Jovi, LL Cool J, Slick Rick, Sisqo, and Fefe Dobson.

After 9 years at his post at Island Def Jam, Clark ventured out and started Tour Managing. He traveled around the world to Japan, Germany & France for 2 years w/ Hoobastank and Christina Milian before he was brought into Atlantic Records as A&R by the labels President Craig Kallman.

In 2006 Clark was offered an executive A&R position at Sony Music where he developed and signed new artists. He also jumped on board to run a production company for The Black Eyed Peas' Printz Board called Beets & Produce, where he was able to develop singers, producers & songwriters. Clark shortly after accepted the post of GM at The Writing Camp, which housed songwriters and producers responsible for hit songs such as Beyonce's "Halo" and Rihanna's "SOS". Clark was also is a producer on the The Hub's hit TV show Majors & Minors.
