The Philadelphia Inquirer's Dan DeLuca says that Jonny Greenwood's There Will Be Blood score is a must-have for die-hard Radiohead fans. DeLuca writes that with the score, Greenwood "extends Radiohead's art rock into the classical realm." The reviewer calls the music "a natural extension of the Radiohead aesthetic as well as a harbinger of a busy-as-he-wants-to-be movie-music-making career for Greenwood."
