Kings of Leon
Any converts to the sound pumped out by Grammy-winning, platinum-selling rocksmiths Kings of Leon when they helped headline the Rock for Oklahoma benefit concert in July won’t have to wait long for a fresh dose: The propulsive single “Supersoaker” is available already, and serves as an advance taste of the joyously, raucously loud pleasures to come on their impending sixth album. “Mechanical Bull” drops September 24; get ready to turn the volume way, way up.
