HBO billed FLIGHT OF THE CONCHORDS as "New Zealand's Fourth Most Popular Folk-Parody Duo" when the premium cable channel debuted their self-titled sitcom in 2007. Since then, thanks to Jemaine Clement and Bret McKenzie's deadpan hilarity and "Flight of the Conchords" music video sequences – perfect for viral sharing – the two have become pop icons in their own right. Expect their sold-out show to include signature rockers like "She's So Hot (Boom!)" and "The Most Beautiful Girl (In the Room)." The show also features Kristen Schaal, who plays the band's fan/stalker, Mel. $38.50. 8 p.m. Fox Theatre, 660 Peachtree St. 404-817-8700. www.foxtheatre.org.
