Heartbreak Kings.

This article presents information on the music group Kings of Leon. For all their success overseas, the Kings are still relatively unknown at home. Their first album, "Youth and Young Manhood," sold around 750,000 copies outside the U.S. and just over 100,000 copies in Great Britain, another album "Aha Shake Heartbreak," is out this month in the United States, debuted at number 3 on the British charts in October 2004. But the band's stateside prospects got a sudden boost last month when the hand was selected as the main support act for U2's spring tour.
