With everyone getting in on the Atkins craze -- we hear that the U.S. Postal Service is ready to issue low-carb stamps -- it's about time for the backlash. Cue the Affairs. This quartet cranks out high-energy power pop that pays glorious homage to the aggressive yet sugary sounds of past masters such as Superchunk, the Buzzcocks and the Who, sweetened by the crystalline vocals of bassist Anne Snyder. Pick up the Affairs' debut single when it comes out this spring: You may pack on a few extra impact carbs, but you'll get a hell of a workout.
