「這個時代每個人都像座孤島，在汪洋中各自漂泊，任憑海水沖刷恣意帶走所有過去，照單全收洋流的餵養直到無以復加。悲鳴不需要語言，活著不等於存在，我們就佇立在汪洋之中，相互遙望。」
羣島成立於2015年台灣，團名取自位於澎湖的漁船船名，ARCPLG 則來自羣島一詞英文學名Archipelago音節縮寫。雙主唱配合五人編制，後龐克為基底輔以變奏混合多樣曲風元素的全創作樂團。羣島以變拍、複合性編曲風格見長，在旋律上，期待每一次的創作都能有新鮮的聽覺體驗，歌詞內容則專注於觀察到的當代風景和自我認同等，期望藉由音樂來表現羣島風格的世代語言。
ARCPLG, an abbreviation of Archipelago, is a name inspired by a fishing boat they saw in Peng-Hu county, Taiwan. This duet-vocal band consists of five band members. Other than the influence of Post-Punk, they also mix their music with variations in rhythm and elements form other music genres. Their lyrics focus on the observation of contemporary society and self recognition, hoping their music could represent the generation of themselves and giving out a brand new hearing experience with their every artworks.
