If it helps: The instrumental line up is a classic 'American Big Band'. Everyone's there, the saxes, trumpets, trombones, keys, bass and drums. It's fast, in a swing style, I'm guessing it's going to be a 1920s-1930s sort of thing. The trombones are punchy and they're accenting the off-beat after the saxes do their soft "dun dun da da-dun" thing.
The vocal range looks like it's an Alto singer, so a jazzy tune with a swing beat, and a lower female voice. Db major key from a first glance.
I wish I could upload something ...
What sort of grand strategy would have big band jazz music as its first clue? Could we really be getting Vicky 3? Or is it an espionage grand strategy? Maybe Cold War?
