Midnight Rebel is a blend of Sumatra Mandheling, Brazilian Santos and Kenya AA coffee beans, roasted rather darkly. It's minorly famous in Back In The Day stories told about the MIT 24-hour Coffeehouse.
Though that worthy institution is no more, and the pale shadow in its place sells Equal Exchange organically llama-filtered coffee, Midnight Rebel is apparently still available from Green Dragon Authentic Coffees.
