Kings Of Leon were riding high on a huge wave of success when it seemed to come crashing down around their ears with lead singer Caleb’s health issues. Now, the band is back with a sixth studio album, and they are getting good reviews.

By the summer of 2011, the band had been touring for nearly a decade, and while their fan base was still steady and ever-growing, the guys were tired. No one felt it more than Caleb, whose voice was in such bad shape that his doctors told him he was one show away from damaging his vocal chords forever. The news came after a show in Dallas, during which Caleb left the stage and didn’t return. His bandmates–brothers Caleb and Jared Followill, and cousin Matthew–were pissed.

“I think, at first, we were all pretty tough on Caleb backstage that night. We were definitely angry,” drummer Nathan said of his younger brother. “At the time, we didn’t realize how severe it actually was, healthwise, for him.”

After a two-year period of rest, the band went back into the studio to record Mechanical Bull, and the album is getting good reviews. The band was invited to “Good Morning America” today and performed live in front of a screaming audience, something the boys must have missed. And while some are calling it a “comeback”, for many fans it’s just been a brief hiatus.
