If you’ve been around the live sound industry for more than a few years, you’ve almost certainly heard of legendary sound company Showco. And if you’ve been active at all on LinkedIn or other social media lately, you’ve very likely seen a lot of activity from the Showco Archive Project. This online catalog of all sorts of amazing bits of Showco history caught our eyes, and we knew we had to get the rest of the story! This episode is sponsored by Allen & Heath and RCF.
This week, Sean and Andy are joined by Indigo Kretzschmar-May, founder and curator of Showco Archives, an ongoing preservation project dedicated to documenting the people, stories, artifacts, and backstage culture behind one of the most influential live sound companies in music history. Indigo grew up in and around Showco alongside her father, Showco sound engineer (and Lynrd Skyndyrd plane crash survivor) Donnie “DK” Kretzschmar to share a look at Showco’s history, the archives, and more!
Joining Indigo is Mike “Dr. Funk” Ponczek, also of Showco, whose career in live audio spans nearly five decades (and counting!), including mixing for The Who, The Kinks, Eric Claptop, and Paul McCartney, and continues today working at Dallas’s Kessler Theater.
