Brigitte Thum is a force of natural charm. She darts like colorful dragonfly through Tucson's media garden, a fluttering, bright distraction worth watching for. Recently she's held down a DJ slot at KXCI. A few years ago, the Lonely Hearts Club lived briefly as a monthly comedy fling, matching love letters to YouTube videos at the Loft Cinema. Now it's a podcast full of delight, music and fun with local guests and their letters.
