Lost Eden was a Japanese hardcore/metal group. Japan’s LOST EDEN came together in 2000 when Norio(Vocals), Adachi(Guitar), Run(Guitar), Daisuke(Bass), Chang(Drums) decided to form a group. The band’s first milestone was in 2002 when they had one song included on the compilation album “SURPLUS SUPPRESSION 3”. In the spring of 2003, Sensyu joined as their new drummer, and Chang switched to guitar. This new 3 guitar line up immediately hit the studio to record their debut single "SEWN MOUTH FOREST" as they continued to fuse their metallic hardcore sound with black and death metal elements.
