Dubsidia Concert History

The summer of 1798, two elderly English musicians and farmers called Daisuke (大辅) Lekker and Yu (ゆう) Benson (they are Japanese descent). They fell unconscious touching a magnet stone semicircle shaped where they could read something set in stone: "Subsidy for you " (Then possibly the stone was a payment of any owner to the church). And they had a strange dream, where they could see and hear the future of centuries later.
