In August 2013, American rock band Kings of Leon—led by Caleb Followill and at the peak of their tour supporting Mechanical Bull (2013)—performed an exclusive concert at O2 Shepherd's Bush Empire in London, a 2,000-capacity intimate venue where their show formed part of the American Express Unstaged series in partnership with VEVO and YouTube, directed by Fred Armisen. The 90-minute performance on August 9, captured professionally and streamed online, caught the band at full strength: Matthew and Nathan Followill's guitar riffs backed Jared Followill's bass and Nathan's drums, while Caleb's raspy vocals added emotional depth with southern charm. Running through "Supersoaker", "Temple", "Fans", "Pyro", "Sex on Fire", "Use Somebody", and "Black Thumbnail"—a mix of stadium rock with melancholy and energy, where the intimate atmosphere amplified the audience connection. This gig—a standout tour moment—showed their stadium power in club format.
