F.I.R. (飛兒樂團) is a popular Taiwanese music group. Renowned producer Ian Chen formed his own band and recruited the other two members to form F.I.R. They are well known throughout Asia with their hit "Lydia," which was the theme song for the Taiwanese TV drama "The Outsiders (鬥魚)." The drama was aired in Taiwan without revealing the singer of the theme song. Having a beautiful voice that asked for attention, the song attracted many fans, leading to F.I.R.'s big success when they finally debuted in 2004.
The name F.I.R. comes from the initials of the names of the three members: Faye, Ian, and Real. Yet it is also an acronym for "Fairyland in Reality."
Some may not know, but Faye and Jolin Tsai (蔡依林) were classmates in college where they studied English together.
