Sonic Boom Rise of Lyric DLC - The Legend of Sonic Jr - Cairo 2026

After the release of "Sonic Boom: Rise of Lyric", Christopher Nolan and Bob Rafei announced that Hans Zimmer would be composing the music for the new DLC content (called "The Legend of Sonic Jr") which takes place before the game, without Richard Jacques. On October 25, 2013, Pharrell Williams revealed to Billboard that he would co-compose the score with Zimmer. Nolan, Rafei and Zimmer (who is previously helped with Marc Webb) formed a supergroup with Williams, Johnny Marr, Mike Einziger and former Eurythmic, David A. Stewart, to create the music for the DLC content. Eventually, Stewart did not participate in the DLC of the video game's music, and the supergroup, credited as The Magnificent Six (a reference to the Sinister Six) was composed of Williams, Marr, Einziger, Junkie XL, Steve Mazzaro and Andrew Kawczynski assisting Zimmer.

Also the additional music was later composed by Arturo Sandoval, Czarina Russell, Andy Page, Adam Peters and Ann Marie Simpson. Later the song appeared in the end credits which is called "It's On Again" which features the vocals by Kendrick Lamar and Alicia Keys. Keys announced the song on Twitter and credited Zimmer and Williams, along with Lamar and herself for the song, indicating the song as a part of the DLC for the video game's soundtrack. Nolan and Rafei described the song as “upbeat and exciting”.
