The first time I heard Glenn Miller’s “In The Mood” was in a Chips Ahoy! commercial, the perfect soundtrack to a cookie factory gone mad. Big band music is so dang fun - it’s expansive and dynamic, the first pop music I can genuinely picture a room full of people dancing to. Get down to thrilling coordinations from the killer ensembles of Count Basie and Benny Goodman, and swoon to stormy melodies like “Brazil” and “Jeep’s Blues.”
