 Original bass player Masayoshi Yamashita was replaced with Taiji Sawada and the American vocalist Mike Vescera with former Ezo singer Masaki Yamada.The sound of this album is much more aggressive and the rhythms much faster than the preceding offerings from the band.This fact has been interpreted as a reaction by composer and producer Takasaki to the many compromises he had to accept by US managers and producers to remain in the record market in the United States.
