Bonnaroo-staples Kings of Leon will release _ Only By The Night_ on September 23. The groups fourth album, Only By The Night, was recorded at Blackbird Studios in Nashville, TN, and was produced by Angelo Petraglia, Jacquire King and Kings of Leon. The group completed work on the album following a busy 2007, which found the family outfit playing sold-out gigs at venues like New Yorks Radio City Music Hall and Los Angeles Greek Theatre. Kings of Leons most recent album, Because of the Times, hit stores in March, 2007. The quartet will play select festivals and headlining shows this summer, including Glastonbury, V Festival and All Points West Festival.
