Zach performed solo all over the Southeast until being called to play in the rock band, Ultrasonic in 2003. Ultrasonic was under Matchbox Records out of Austin, TX which soon became home. After about 6 months in Austin, the band was approached by an agent about representation and before long he started moonlighting as an agent for the company for many classic rock artists. After a year, Zach went out on his own creating The Jiles Agency where he exclusively represented the legendary, Leon Russell for the subsequent 8 years.
Under his company he also worked with artists such as; Jason Aldean, Mark Chesnutt, Florida Georgia Line,Mark Wills, Parmallee, Gary Hoey, Pat Travers, Rick Derringer, Commander Cody, and Adam hood amongst others. In 2006, Zach had the pleasure of joining the Texas rock band, Vallejo and for the following 2 years he toured all over the country while simultaneously running The Jiles Agency. Now, Zach resides in Nashville, TN where he plans to stay working as a Consonant Committee Member.
