The Texas International Pop Festival, held over Labor Day weekend in 1969, stands as one of the most legendary music events in Texas history. Organized by Showco founders Angus Wynne III and Jack Calmes just weeks after Woodstock, the festival brought together more than 120,000 fans in Lewisville, Texas, for a three-day celebration of rock, blues, and counterculture.

With a lineup that included Janis Joplin, Led Zeppelin, B.B. King, Santana, Sly & the Family Stone, and many more, the festival not only showcased iconic performances but also marked a turning point for live music production in the South. Behind the scenes, Wynne and Calmes’s innovative approach to sound and staging—along with the debut of Showco’s early technology—helped set new standards for concert experiences nationwide.
