"This album was released under the alias "Undercover Express" in Japan & was intended as a sideproject, not as a new Osaka Monaurail release. That's why it is easy to underst&, how this album differs from the other releases. It's all instrumental cover-versions, & the overall sound is cleaner & jazzier than the typical Osaka Monaurail-sound. German distributor Unique Records decided to go with new grown popularity of Osaka Monaurail in Europe due to their incredible live-shows, that they have played in Europe for at least three years in a row at the time of this release, & released this as "Amen Brother" by Osaka Monaurail. Not aware of the story of this album, some listeners showed disappointment in the record (saying it was too different from it's predecessors due to the points mentioned above), but were convinced by the live-experience once & for all, which had this "misunderst&ing" lose it's importance."
