Which band performs the song "Immortals" on the "Big Hero 6" soundtrack?

Fall Out Boy performs the song "Immortals" on the Big Hero 6 soundtrack.

Disney commissioned the American rock band to write and record the original song for the 2014 animated superhero film. "Immortals" is heard as Hiro, Baymax, and their friends transform into the technologically enhanced Big Hero 6 team, giving the sequence an energetic pop-rock lift.

The song was written by Fall Out Boy members Patrick Stump, Pete Wentz, Joe Trohman, and Andy Hurley. It was released as a digital single on October 14, 2014, shortly before the film's theatrical release. The band later included an alternative version on its 2015 album American Beauty/American Psycho.

One common source of confusion is that Big Hero 6 also has a substantial orchestral score. Henry Jackman composed that score, but he did not perform "Immortals." Fall Out Boy's song is the film's prominent original rock song, while Jackman's music supplies the instrumental dramatic material.
