X:IN - Chain Reaction - PLATFORM Version

X released their first full-length album, Chain Reaction, digitally on October 6, 2026, through BeBy Entertainment. Featuring eleven tracks, the collection explores how different musical styles, emotions, and creative partnerships can interact to produce something new. Its chemistry-inspired concept connects songs such as “Brain Chemistry,” “Chemical Moment,” “H₂O,” and “pH7,” presenting the album as a sequence of encounters and transformations that expands the group’s musical identity.

Opening track “ZZIRIT” features Brazilian artist Luísa Sonza, while “Neurotox” introduces a collaboration with tiLLie. These guest appearances bring additional voices and perspectives into the collection, reflecting its emphasis on connections across languages and cultures. Alongside “Octane,” “Tempered Steel,” “Zero Kelvin,” and “Boom! Crash,” the tracklist develops the album’s scientific imagery before closing with a Hardbass Remix of “Girls On Fire.”

All five members participated in writing lyrics, giving Chain Reaction a personal foundation alongside its external collaborations. Aria holds credits on “Brain Chemistry” and “Boom! Crash,” while Nova contributes across several tracks, including “Octane” and “Chemical Moment.” Nizz and Hannah appear among the lyricists for “Tempered Steel” and “Zero Kelvin,” respectively, with E.sha and Hannah contributing to “H₂O.” For listeners following X’s development, this first studio album marks a substantial step into a wider range of sounds and creative exchanges.
