Japanese rock band fronted by Takanori Nishikawa (T.M.Revolution). Formed in 2005, the band was named after Abingdon School, the all-male school where English rock band Radiohead (whom a.b.s. are modelled after) was established. Their major label debut single, INNOCENT SORROW (2006), was used as the first opening song of anime series D.Gray-man.
