Meaning 'the Universe and I' or 'You and I' in Chinese characters, Pia was originally formed by Hullang Lee (guitar), Kibum Kim (bass) and Yohan Ok who were later joined by Simz No and, after several member changes on drums, Hye Seung Yang (drums). The band has maintained this line-up ever since their first official gig together, the 2001 Ssamzie Festival.
