Kings Of Leon Say New Album is 'Darker'

Speaking with Billboard.com last month, frontman Caleb Followill said that the band's sound expanded for the album, with instruments such as the fiddle, trumpet and lap steel featured on different songs. "I think every one of them really complements the songs," he said, "and I think having done that, it's really gotten us excited for the future and where we can go with the band and what we can do." 

After "Night" earned four Grammy Awards and spawned smash singles "Use Somebody" and "Sex on Fire," the Southern rockers hammered out new tracks in New York last February before headlining Bonnaroo in June. "Sundown"'s track list has not been released, but the group has been playing new songs with working titles like "Immortals," "Mary" and "Radioactive" on tour this summer.
