Following up a reunion gig this past October, fake band Hep Alien has once more slipped the bonds of fiction, playing a surprise gig at the ATX Television Fest. Blurring the made-up geography separating Stars Hollow, Connecticut and Dillon, Texas, the Gilmore Girls trio of Keiko Agena, Todd Lowe, and John Cabrera ran through a brief set of covers at a screening of the Friday Night Lights episode “Mud Bowl.” Appearing in-character, the group opened with songs by Blondie and The White Stripes (with a wink to the disastrous TV house party that kicked off its TV career), before throwing curveballs that included a countrified “Single Ladies” and a roughed-up version of Gilmore Girls’ theme song, “Where You Lead” by Carole King.
