With his soothing voice, Paul Slavens sounds like your standard National Public Radio personality. But Slavens is so much more. He's a composer, an improv musical comedy genius (his Monday night residency onstage at Dan's Silverleaf in Denton is becoming legendary) and, best of all, a go-to source for locally produced songs and long-forgotten gems. He comes to his knowledge rightfully as the former frontman for the jazz-rock combo Ten Hand, an act that once graced the stages of Deep Ellum. But now that he's older and, um, balder, he remains entrenched in the local scene thanks to his calming, end-of-the-weekend, listen-and-let-the-world-slow-down-for-a-second radio show.
