Seven years after their unprecedented arrival in the UK, they are finally making a name for themselves overseas, thanks to a series of hit albums and singles (peaking with 2008's anthemic "Sex on Fire") and a headline slot at Glastonbury in 2008 and at Reading in '09. No longer indulging in the drugs which were threatening to come between them, the band are older, wiser and in a better position to reflect in their rise to glory. Their's is a unique tale, from their youth as touring musicians in their preacher father's church to their discovery by the American music industry and beyond. Joel McIver's new book, the first ever Kings of Leon biography, digs deep into their history to reveal a band like no other.
