Musical styles come and go, then often come back again later. And while their later incarnations lack the examination of unexplored artistic ground, they're often better representations of the earlier styles they emulate.
Consider the Stray Cats, one of the best rockabilly bands, but one who put out their first record in 1981, a full 20 years after the style's heyday. The Darkness arguably understands '80s hair rock better than some of the bands that created it before their hair fell out. And though indie-folk got its start with '60s guitar pop, the levels it has reached now are far more interesting, despite being less innovative.
Continuing that tradition, are the Prids, heirs to the throne of Joy Division-style New Wave: dark and moody, with washes of sound and a kickin' beat. They aren't one of the bands that created the style, but they understand it well enough to make it all it can be.
