Emmylou Harris and Jessica Lea Mayfield are among the artists who will be showcased on the PBS special ACL Presents: Americana Music Festival, along with Robert Plant, Gregg Allman, Alison Krauss, The Avett Brothers, and others, airing on Austin City Limits this Saturday, November 19, on PBS stations across the United States. The hour-long special was filmed live at the Ryman Auditorium in Nashville on October 13, during the sold-out Americana Music Association's Honors and Award Show, at which Mayfield was nominated for New/Emerging Artist of the Year.

Hosted by Jim Lauderdale, with the Americana All-Star Band led by frequent Emmylou Harris collaborator Buddy Miller, the show runs the Americana gamet, beginning with the opening of "I'll Fly Away," a tribute to the O Brother Where Art Thou? soundtrack, featuring Harris and Alison Krauss. Jessica Lea Mayfield joins the All-Star Band for a performance of her song "For Today," of which you can catch a sneak peek in the video below.
