As previously announced, the show is being headlined by the Grammy award-winning duo Gnarls Barkley. The genre busting act's first US concert was a MySpace Secret Show, in the halcyon days of 2006. For this show, the group will be performing at Manhattan's famed Fillmore New York at Irving Plaza and will be joined by the indie rock super group Battles.

Gnarls Barkley is the much beloved combination of artist and producer Danger Mouse and vocalist Cee-Lo Green. The duo recently released The Odd Couple, featuring the singles "Run" and "Going On," is the follow up to the group's platinum-plus selling debut album St. Elsewhere, which was not only critically lauded but a chart-topping worldwide blockbuster. St. Elsewhere was nominated for seven Grammy Awards, with the band receiving trophies for Best Alternative Album and Best Urban Alternative Performance.

Opening act Battles is comprised of the former members of Don Caballero, Helmet, Tomahawk, and Lynx. Featuring Tyondai Braxton, Ian Williams, John Stanier and Dave Konopka, Battles have long since been touted as an "indie rock supergroup." Following their signing to Warp Records and the release of two EPs in 2006, the band released their long awaited first album Mirrored. Pitchfork raved about Mirrored as "a breathtaking aesthetic left-turn that sounds less like rock circa 2007 than rock circa 2097, a world where Marshall stacks and micro-processing go hand in hand."
