Bump of Chicken was a highly successful Japanese rock act that formed in 1994 for a high school 'cultural festival.' Members Motoo Fujiwara (vocals and guitar), Hiroaki Masukawa (guitar), Yoshifumi Naoi (bass), and Hideo Masu (drums) all met each other as youngsters at school, and would eventually release their first album, Flame Vein, in 1999 with High Line Records.
