Kings of Leon's sound may have changed over the years, but their knack for killer tunes hasn't. When the Nashville act first hit the garage rock scene in the early ‘00s, their mix of sassy ravers and shaggy twang had fans hailing them as the Southern-fried Strokes. By 2008's Only by the Night they had evolved to arena-scale rock blown out with cascading guitars and production as vast as America's heartland. Caleb Followill's husky, passionate growl is one of the band's signature traits; as the 2013 anthem “Supersoaker” proves, it's an instrument that has only grown more subtle with time.
