Pop Underground is power-pop that came after the original golden age of power-pop in the '70s and very early '80s. The main difference is time period, so Pop Underground is still distinguished by power-pop's hallmarks -- sweet British Invasion melodies and harmonies, ringing but muscular guitars. Yet because Pop Underground extends the life of a form whose most vital stages of development are past -- and a form that was already classicist to begin with, at that -- its artists either update the formula with contemporary twists, or simply re-create that formula to the best of their ability.
