Episodes. <onlyinclude></onlyinclude> Production. Development. During February 2018, episodes of "The Simpsons" were held back to avoid competing with the 60th Annual Grammy Awards, Super  Bowl LII, the 2018 Winter Olympics, and the 90th Academy Awards. This resulted in a nine-week gap in between new episodes, and is the second season to not have any new episodes airing in February, after the twenty-fifth season (which also aired in a Winter Olympics year). Casting. The season features guest appearances from Norman Lear, Martin Short, Ray Liotta and Nikolaj Coster-Waldau. In addition, Bill Plympton animated a sixth couch gag in "3 Scenes Plus a Tag from a Marriage", having previously done so in season 23's "Beware My Cheating Bart", season 24's "Black  Eyed, Please", season 25's "Married to the Blob", season 27's "Lisa the Veterinarian", and season 28's "22 for 30". This season also features Kelsey Grammer reprising his role as Sideshow Bob and Homer seeking help from Shaquille O'Neal ("Gone Boy"), and a song written by guest star Rachel Bloom ("Springfield Splendor"). The season also includes the Simpson family traveling to New Orleans for JazzFest ("Lisa Gets the Blues"), and an episode that reimagines Stephen King's "It" featuring Krusty the Clown ("Fears of a Clown"). Music. On August 30, 2017, it was announced that longtime "Simpsons" score  composer Alf Clausen was let go from the series. The series switched from a live orchestrated score to a produced score by Bleeding Fingers Music.
