Music

There is a lot of music associated with the ChäoS;HEAd visual novel, its anime, its enhanced remake, and its romance comedy spinoff game.

Also, the in-game band Phantasm and its singer FES are credited with many songs, not just in the ChäoS;HEAd franchise, but also in later games and anime in the larger Science Adventure Series franchise that ChäoS;HEAd is a part of.

Non-ChäoS;HEAd Phantasm songs[]

The Japanese voice actress who plays Ayase Kishimoto (as well as her stage persona FES, singer for the fictional band Phantasm), Yui Sakakibara, is also a musician. She has performed quite a few songs written for various games and anime in the Science Adventure Series. She has released 2 albums as FES/Phantasm with music performed for these games : ~PHANTASM~ End Prophecy released by Media Factory on May 6, 2009 and ~PHANTASM~ Revival Prophecy released by Media Factory on December 21, 2011.

Yui Sakakibara has done real-life concerts cosplaying as FES. She has had a number of singles out along with her 2 FES/Phantasm albums, and her full discography as FES is available here for music credited to FES and here for music credited to Ayase Kishimoto (Yui Sakakibara’s other non-FES related music is not at those 2 links). Rend the Darkness of My Heart is the only song she did as Ayase Kishimoto’s true personality; the other songs were all done as Ayase’s stage persona FES.
