Now, you might not be interested in Big Band music, but that's where all of swing comes from. Most of the music does not come off as "high energy" like Neo-Swing for two reasons: 1) Recording technology wasn't great back then, and 2) It's hard to capture the energy of a big band on a recording, even today; however, the best dances I've ever been too have been with a full 20 piece big band!

Regardless, you should check out these required songs from the Big Band Era:

Andrews Sisters - Bounce Me Brother with a Solid Four
