Taking in a show at Dwight Mark's charming home in Highland is more like attending a friend's dinner party than seeing a concert at a formal venue. Prior to the performance, folks nosh on light hors d'oeuvre and chat, then eventually make their way to the living room for intimate, one-of-a-kind performances by an array of engaging acts, from celebrated local talent to well-regarded imports. And while the idea of living-room concerts might alarm the neighbors, Mark is careful to keep the music at a reasonable level — so much so that when you're standing on the porch, you can only faintly hear the sounds coming from inside. Props to Mark for a unique experience.
