It’s cool what you can learn about people with whom you do business, if only you ask and listen. Today in Houston I met with David Thompson, a filmmaker and creative director; we have a mutual client in Houston and have forged a friendship over the years. Turns out his first career was in music. He founded Justice Records, an independent label in Houston that released records by Kris Kristofferson and Waylon Jennings in the mid-’90s. His proudest discovery was Tab Benoit, who blends East Texas blues with Cajun spice.
