The music industry, more than any other, is known for its constantly changing astrology. There are those few stars that have found a permanent home in the shifting constellations of music history—indelible pinpricks in the sky, whose perfectly coiffed and carefully managed images take years to arrive down on Earth. And even after they die, or disband, or otherwise go gently into that good night, their fame lingers like a beacon, their traveling reservoir of light not yet up. But more often, new artists are nothing but shooting stars. They appear suddenly and vanish just as suddenly.
