With the recent tease of "Globesmen," a spot-on homage to the 1968 documentary Salesman, we know we're in for a treat when the second season of IFC's critically-acclaimed series Documentary Now! returns this fall. Today, IFC released news of another upcoming episode and even more comedic talent joining the mix.

Actress and comedian Maya Rudolph (Saturday Night Live, Maya & Marty, and IFC's own The Spoils Before Dying) will co-star in a music-centric episode of Documentary Now!. In "Test Pattern," Rudolph joins series' regulars Fred Armisen and Bill Hader on the stage as they perform one of the greatest concerts that never really happened.

Inspired by the groundbreaking 1984 Talking Heads concert documentary Stop Making Sense, "Test Pattern" features an eponymous hit band (Armisen, Hader and Rudolph) performing a riveting, high-energy final concert to an eager audience of fans. The innovative episode includes a musically-diverse set list of songs written by Armisen himself. (Just like last season's hummable tunes from the Blue Jean Committee.) Outside of the concert, the episode will delve deep into the musicians' interwoven backstories and reveal the inspirations behind their '80s classics such as "Free David Ness" and "Indeng Indeng."

"Test Pattern" joins the four previously announced titles "The Bunker," "Globesmen," "Juan Likes Rice and Chicken," and the two-part Hollywood-themed doc "Mr. Runner Up," all premiering on IFC this fall.

While you wait for the fictional concert of a lifetime, catch up on the entire first season of Documentary Now! with a marathon this Sunday starting at 10A. Season 2 premieres with seven new episodes this fall on IFC.
