Kings of Leon will be the next artist to participate in the American Express-sponsored concert series Unstaged. The group’s August 9 performance will be streamed live from Shepherd's Bush in London at 4 p.m. ET/1 p.m. PT at AmexUnstaged.com.  Directing the event will be former Saturday Night Live star Fred Armisen.

If you want to check it out, you can join the audience on the web, or via YouTube and VEVO apps for iPhone, iPod touch, iPad and Android. The show takes place about six weeks before Kings of Leon’s new album, Mechanical Bull, arrives in stores on September 24.
