Electronic Bach: "Et in unum Dominum" from Mass in B Minor, 8-bit style

This gorgeous duet from the Mass has some really interesting twists in harmony towards the end, fascinating stuff. Lyrics: Et in unum Dominum, Jesum Christum, Filium Dei unigenitum et ex Patre natum ante omnia saecula. Deum de Deo, lumen de lumine, Deum verum do Deo vero, genitum, non factum, consubstantialem Patri, per quem omnia facta sunt. Qui propter nos homines et propter nostram salutem descendit de coelis. (And in one Lord Jesus Christ, the only-begotten Son of God, begotten of his Father before all worlds. God of God, Light of Light, very God of very God, begotten, not made, being of one substance with the Father, by whom all things were made. Who for us men and for our salvation came down from heaven.)
