Kings of Leon's eclectic rock ‘n' roll—a mix of hip-shaking Americana and ebullient pop—has spawned diverse disciples. The Lumineers touch on the brothers' early, earthy vibes with “Sleep on the Floor”; The Raconteurs' slinky “Level” unleashes meaty, funky guitar hooks; and George Ezra's love tune “Budapest”—with its bouncy melody and soulful delivery—recalls KoL's poppy, rough-hewn energy.
