Geezers Of Gear Episode #353

Indigo is the founder and solo operator of Showco Archives. As the daughter of legendary senior Showco sound engineer Donnie 'DK' Kretzschmar, she grew up surrounded by the history of the crews who built stadium touring from scratch. Today, she meticulously catalogs thousands of legacy artifacts and spearheads the campaign to induct Showco into the Rock and Roll Hall of Fame.

Jonny is a legendary monitor engineer. Over a four-decade career, Jonny has shaped the live sound for an unparalleled roster of icons—including Jackson Browne during the Running on Empty era, Genesis, The Who, and The Bee Gees—capping off his journey behind the console for Van Halen’s final tour.

Blake is the reason your ears were ringing, as a premier sound guy for the legendary Showco, he was on the front lines of live music’s loudest era. We’re talking Van Halen in their prime, The Who, Aerosmith's reunion, and Bad Company. He mixed the smooth soul of Frankie Beverly & Maze, the outlaw country of Waylon Jennings, and the heavy metal madness of Mötley Crüe, Ratt, and Bon Jovi.

Archivist/Solopreneur

I’m the founder and solo archivist behind [Showco Archives](https://www.showcoarchives.com?utm_source=chatgpt.com), an independent preservation project centered on “The Family Behind the Music.” As the daughter of longtime Showco sound engineer Donnie “DK” Kretzschmar, I grew up surrounded by the people, stories, and culture that helped define rock ’n’ roll touring. Through oral histories, rare memorabilia, backstage ephemera, and alumni stories, I work to preserve the human side of SHOWCO. This pioneering Dallas-based concert sound company helped shape modern live sound and touring production. Proceeds from the archive support preservation efforts, Showco alumni, and music industry charities including MusiCares and Sweet Relief Musicians Fund.
