In 2008, Kings of Leon released its fourth studio album, "Only by the Night", produced by Jacquire King and Angelo Petraglia on September 19, which subsequently entered the UK Albums Chart at number one and remained there for one more week. "Only by the Night" also had two single-week stints as the UK number one album in 2009, one directly after the BRIT Awards. In the United States, the album reached number four on the "Billboard" 200.
