Southern rock ‘n’ rollers, Kings of Leon, shook Summerfest, headlining The Marcus Amphitheater.  Brothers Caleb (lead vocals & guitar), Nathan (drums/percussion), and Jared Followill (bass), along with their cousin Matthew Followill (lead guitar) have long been touring in support of 2013’s Mechanical Bull, but prior to their Milwaukee show, Kings of Leon revealed they’ve been working on their seventh studio album… so perhaps Milwaukee will see KOL again, sooner rather than later.
