How many sons of Pentecostal evangelical ministers do you know grow up to headline arena tours? I can only think of three, Caleb, Nathan, and Jared Followhill of the critically acclaimed southern rock group Kings of Leon. In 1999, The brothers along with cousin Matthew Followhill formed the band in Tennessee and produced the EP Holy Roller Novocaine four years later. Fast forward to the summer of 2009 when it seemed nobody could get in the car without hearing Caleb’s throaty growl in the ubiquitous Sex on Fire. Watch KOL conquer stages and models (congrats to Caleb and Lily) in Talihina Sky, a documentary featuring unseen footage and interviews charting the band’s growth from modest beginnings in the Bible Belt to their very own MTV Cribs episode. The film airs on Showtime August 21, 2011, 10 pm EST.
