Inevitably, the holidays are a time when robotic prog-rock monstrosities like Mannheim Steamroller and varying grades of sentimental crooning get a lot of play over radio airwaves, television ads and department store public address systems. But Vince Guaraldi’s A Charlie Brown Christmas — one of the coolest Christmas albums ever made — was itself created for a 1965 animated special, which is proof that festive music made for mass consumption isn’t always a bad thing. It’s become tradition for The Ornaments — featuring keyboardist Jen Gunderman in Guaraldi’s spot, along with bassist James Haggerty and drummer Martin Lynds — to work their way through the perennial jazz favorite twice a night for a week or so at the Family Wash. This year they’re adding shows at Mercy Lounge and a Saturday morning show for kids at The Belcourt. Here’s to wry instrumental humor, stylish understatement and emotional complexity, even if it’s made for TV.
