FIESTER這個樂隊名稱源自西班牙語中的「fiesta」，意思是狂歡節或派對。樂隊成員選擇這個名稱是希望將節慶和生氣勃勃的能量帶入他們的表演和音樂中。他們希望聽眾能從中找到擺脫壓力和困難的新出路，像體驗狂歡節的興奮和歡樂。樂隊還在音樂中展現年輕女性的獨特觀點，希望能與聽眾共鳴。

The band's name, "FIESTER," is derived from the Spanish word for "carnival," reflecting their goal of creating a festive and energetic atmosphere through their music with a mix of heavy metal and electronic elements. The band has been making waves in the music industry with their unique blend of electronic core rock and the Cantonese language.
